<Overview of Communication System S>
FIG. 1 shows an overview of a communication system S according to this embodiment. The communication system S is a system that enables a manager, an operator, or the like of the flying object 10 to confirm the aircraft identification information, the position, etc. of the flying object 10 using the terminal device 100 at a position away from the flying object 10. . The communication system S includes an aircraft 10 , a base station 20 , a management server 30 , an aircraft information management device 40 , an external terminal 50 and a terminal device 100 .

The flying object 10 is a manned flying object, a remotely operated unmanned aerial vehicle, an unmanned flying object, or the like. The flying object 10 is, for example, a drone. The aircraft 10 has a communication module 11 for enabling communication with the outside through the first communication means and the second communication means. The flying object 10 uses such a communication module 11 to transmit information about the flying object 10 including aircraft identification information for identifying the flying object to the base station 20 and the terminal device 100 .

The information on the flying object 10 further includes, for example, positional information on the flying object 10 . Further, the information of the flying object 10 may include the flight altitude, flight speed, time information, and the like of the flying object 10 . The time information is, for example, the time when the communication module 11 transmits the information on the aircraft 10 .

The flying object 10 transmits the information of the flying object 10 as the first flying object information to the terminal device 100 by using the first communication means, for example ((1) in FIG. 1). The first communication means is a direct broadcast communication means capable of communicating with the flying object 10 without going through a mobile phone network. The direct broadcast system is, for example, the BLE communication system. In this case, the communication module 11 transmits the first aircraft information to the terminal device 100 . It is desirable that the communication module 11 transmit the first flying object information at a substantially constant transmission cycle. A cycle in which the communication module 11 transmits the first flying object information is defined as a first transmission cycle.

Also, the flying object 10 transmits the information of the flying object 10 as the second flying object information to the base station 20 by using the second communication means ((2) in FIG. 1). The second communication means is network-based communication means capable of communicating with the flying object 10 via a mobile phone network. In this case, the communication module 11, for example, transmits the second aircraft information to the management server 30 via the base station 20 ((2) and (3) in FIG. 1). It is desirable that the communication module 11 transmit the second flying object information at a substantially constant transmission cycle. A cycle in which the communication module 11 transmits the second flying object information is defined as a second transmission cycle. The second transmission cycle is, for example, substantially the same cycle as the first transmission cycle.

The base station 20 is a radio station that has an antenna and a transmitter/receiver and is established and installed on land to communicate with the aircraft 10, the external terminal 50, the terminal device 100, and the like. By providing the base stations 20 at a plurality of different locations, it is possible to expand the communicable area. Such base station 20 and management server 30 constitute a mobile phone network. In other words, the base station 20 and the management server 30 enable the aircraft 10, the management server 30, the external terminal 50, and the terminal device 100 to communicate using the second communication means. Specific examples of the second communication means are ground LTE, sky LTE, and the like.

The management server 30 manages information of users connected to the mobile phone network and operates the mobile phone system. A mobile phone network composed of the base station 20 and the management server 30 is provided, for example, for each company that operates communication services using mobile phones.

The aircraft information management device 40 receives from the terminal device 100 the first aircraft information transmitted from the aircraft 10 to the terminal device 100 using the first communication means. In this case, the terminal device 100 transmits the first aircraft information to the aircraft information management device 40 using the second communication means via the base station 20 ((5) and (3) in FIG. 1). The aircraft information management device 40 transmits the received first aircraft information to the external terminal 50 using the second communication means ((3) and (4) in FIG. 1).

The aircraft information management device 40 also receives the second aircraft information transmitted by the aircraft 10 using the second communication means ((2) and (3) in FIG. 1). The aircraft information management device 40 transmits the received second aircraft information to the terminal device 100 using the second communication means ((3) and (5) in FIG. 1). The aircraft information management device 40 also transmits the received second aircraft information to the external terminal 50 ((3) and (4) in FIG. 1). Such an aircraft information management device 40 is, for example, a computer such as a server. Further, the aircraft information management device 40 may be a server integrated with the management server 30 .

The external terminal 50 is a terminal operated by the user of the external terminal 50 at a place other than the place where the flying object 10 is operated and observed (referred to as "site" in this embodiment). Off-site locations are, for example, offices, residences, public facilities, in transportation, on roads, and the like. The external terminal 50 is, for example, a terminal that can use mobile phone services by connecting to the base station 20 . The external terminal 50 may be, for example, a mobile terminal such as a tablet or a smartphone, or may be a personal computer, a server, or the like.

The external terminal 50 receives the first flying object information and the second flying object information of the flying object 10 from the management server 30 through the second communication means. As a result, the external terminal 50 can identify the flying object 10 by the aircraft identification number and obtain information such as the position of the identified flying object 10 outside the field.

The terminal device 100 is a terminal operated by a user of the terminal device 100 at a site or the like. The site is, for example, outdoors, by a window of a building, or the like. The terminal device 100 receives the first aircraft information transmitted by the first communication means from the aircraft 10 near the site ((1) in FIG. 1). The terminal device 100 is a terminal that can be connected to the aircraft 10 by direct broadcasting.

Also, the terminal device 100 is a terminal that can use a mobile phone service by connecting to the base station 20 by a network system. The terminal device 100 is, for example, a mobile terminal such as a tablet or a smartphone.

The terminal device 100 transmits the received first aircraft information to the base station 20 using the second communication means ((5) in FIG. 1). The base station 20 transmits the received first aircraft information to the aircraft information management device 40 using the second communication means. Then, as described above, the aircraft information management device 40 transmits the received first aircraft information to the external terminal 50 .

As described above, in the communication system S according to the present embodiment, the external terminal 50 and the terminal device 100 communicate the first aircraft information transmitted by the aircraft 10 by the first communication means and the second flight information transmitted by the second communication means by the aircraft 10 . body information, respectively. The external terminal 50 and the terminal device 100 can acquire the information of the flying object 10 more reliably by receiving the information of the flying object 10 transmitted by two different communication means. In addition, the external terminal 50 and the terminal device 100 sequentially receive the information about the flying object 10 transmitted by the flying object 10 at substantially constant intervals, so that, for example, the movement of the flying object 10 can be observed. can.

However, for example, the first communication means and the second communication means have different communication schemes, and thus cause different delays. For example, the terminal device 100 directly receives the first flying object information transmitted by the flying object 10 through the first communication means ((1) in FIG. 1). On the other hand, the terminal device 100 extends from the aircraft 10 to the base station 20 ((2) in FIG. 1), from the base station 20 to the management server 30 and the aircraft information management device 40 ((3) in FIG. 1), the management server 30 to the base station 20 ((3) in FIG. 1), and from the base station 20 to the terminal device 100 ((5) in FIG. 1). Therefore, the terminal device 100 tends to receive the first aircraft information faster than the second aircraft information.

On the other hand, if an obstacle or the like is positioned between the terminal device 100 and the flying object 10, the first flying object information cannot be received, or the reception strength decreases and the communication quality deteriorates. Also, when a failure or the like occurs in the mobile phone network, it may become difficult to communicate using the second communication means. Therefore, the terminal device 100 needs to handle information received by both communication methods while considering the communication speed of each communication method. Therefore, the terminal device 100 according to the present embodiment has a simple configuration and can appropriately handle information on the flying object 10 obtained from the flying object 10 by a plurality of communication methods. Such a terminal device 100 will be described below.

<Configuration Example of Terminal Device 100>
FIG. 2 shows a configuration example of the terminal device 100 according to this embodiment. Terminal device 100 includes communication unit 110 , storage unit 120 , display unit 130 , and control unit 140 .

The communication unit 110 is an interface for communicating with the communication methods of the first communication means and the second communication means. The communication unit 110 receives, for example, first flying object information including aircraft identification information for identifying the flying object 10 transmitted from the flying object 10 by the first communication means. The communication unit 110 also receives the second aircraft information including the aircraft identification information transmitted from the aircraft 10 by the second communication means. The communication unit 110 may function as an interface connectable to an external network such as the Internet.

Further, when receiving the first flying object information, the communication unit 110 outputs information on the time when the first flying object information was received as information on the first time. Similarly, when receiving the second flying object information, the communication unit 110 outputs information on the time when the second flying object information was received as information on the second time. For example, when information on the flying object 10 is received, the communication unit 110 acquires time information from a clock circuit or the like in the terminal device 100, and outputs the received time information in association with the received information on the flying object 10. do.

The storage unit 120 is a storage medium including ROM (Read Only Memory), RAM (Random Access Memory), and the like. The storage unit 120 may also include a large-capacity storage device such as a HDD (Hard Disk Drive) and/or an SSD (Solid State Drive). For example, when a computer functions as the terminal device 100, information such as an OS (Operating System) and programs that make the computer function may be stored. Further, the storage unit 120 may store various information including a database that is referred to during program execution.

The storage unit 120 may also store intermediate data generated (or used) by the terminal device 100 in the process of operation, calculation results, thresholds, reference values, parameters, and the like. Further, the storage unit 120 may supply the stored data to the request source in response to a request from each unit in the terminal device 100 . The storage unit 120 stores, for example, information about the transmission cycle of the first flying object information by the first communication means of the flying object 10 . The storage unit 120 may store information on the transmission period of the second aircraft information by the second communication means of the aircraft 10 .

The display unit 130 displays information on the aircraft 10 . The display unit 130 displays, for example, the authentication result of the aircraft identification information of the aircraft 10, the position information, the received communication method, the flight area, and other information. Note that the authentication result of the aircraft identification information is information indicating that the flight of the aircraft 10 has been authenticated in advance by an authentication organization or the like. The flying object 10, for example, includes the authentication result of such aircraft identification information in the information of the flying object 10 and transmits it. It is desirable that the display unit 130 also function as a display for displaying the communication status of the terminal device 100, the OS, the execution status of applications, and the like.

The control unit 140 is, for example, a CPU (Central Processing Unit). The control unit 140 has a first acquisition unit 141 , a second acquisition unit 142 , a determination unit 143 and a display control unit 144 . In other words, the CPU functions as a first acquisition unit 141 , a second acquisition unit 142 , a determination unit 143 and a display control unit 144 by executing programs stored in the storage unit 120 .

The first acquisition unit 141 acquires the first flying object information from the communication unit 110 and the information of the first time when the communication unit 110 received the first flying object information. The first acquiring unit 141 acquires the first flying object information received using the direct broadcasting first communication means capable of direct communication with the flying object 10 .

The second acquisition unit 142 acquires the second flying object information from the communication unit 110 and the information of the second time when the communication unit 110 received the second flying object information. The second acquiring unit 142 acquires the second flying object information transmitted from the flying object 10 using the network-based second communication means capable of communicating via the mobile phone network. Note that FIG. 2 shows an example in which the first acquisition unit 141 and the second acquisition unit 142 are provided in the control unit 140, but instead of this, one acquisition unit is provided with the first acquisition unit 141 and the second acquisition unit It may function as the acquisition unit 142 .

The determination unit 143 determines whether the one second time is earlier than the one second time and whether a predetermined period has passed since the one first time closest to the one second time. judge. Here, the predetermined period matches the first transmission cycle of the first flying object information stored in the storage unit 120, for example. The predetermined period may be a period longer than the first transmission cycle, or may be a constant period stored in the storage unit 120 in advance. For example, the predetermined period is longer than the first transmission period and less than or equal to about twice the first transmission period.

For example, consider a case where the flying object 10 transmits first flying object information in a first transmission cycle, and transmits second flying object information in a second transmission cycle substantially equal to the first transmission cycle. Also, as an example, the flying object 10 transmits the first flying object information and the second flying object information at the same timing. Since the first communication means transmits the first flying object information through direct communication between the flying object 10 and the communication unit 110, the communication unit 110 receives the first flying object information faster than the second flying object information received via the network. Receive aircraft information.

Here, when the communication unit 110 is normally sequentially receiving the first aircraft information, two consecutive first times are times separated by a time interval of the first transmission period. Then, when the communication unit 110 normally receives the first flying object information and the second flying object information, the communication unit 110 receives the first flying object information at the first time, and then receives the first flying object information at the first time. Before one transmission period elapses, one second flying object information is received at one second time. In other words, when the first flying object information is normally received sequentially, the one second time is a time earlier than the one second time and the one closest to the one second time. It is the time before the first transmission period elapses from time 1.

Therefore, the display control unit 144, in response to the determination unit 143 determining that the predetermined period has not elapsed from the one first time at the one second time, displays the first time received at the one first time. Information based on the aircraft information is displayed on the display unit 130 . As a result, the display control unit 144 displays information based on the first flying object information on the display unit 130 when the communication unit 110 is normally sequentially receiving the first flying object information, and displays information with little delay. The user of the terminal device 100 can be made to confirm.

Note that the first flying object information and the second flying object information may include time information at which the communication module 11 of the flying object 10 transmits the information of these flying objects 10 . For example, the first aircraft information further includes first time information indicating the transmission time at which the aircraft 10 transmits the aircraft identification information through the first communication means, and the second aircraft information includes the transmission time when the aircraft 10 transmits the aircraft identification information via the first communication means. It further includes second time information indicating a transmission time at which the device identification information is transmitted by the communication means.

In this case, the determination unit 143 may further determine whether or not the difference between the transmission time indicated by the first time information and the transmission time indicated by the second time information is within a predetermined time difference. In this case, the display control unit 144 displays information based on the first flying object information received at the first time in response to the judgment unit 143 judging that the transmission time difference is within the predetermined time difference. display on the unit 130 .

It is desirable that the display control unit 144 causes the display unit 130 to continue to display the first flying object information until at least the first transmission period has elapsed, until the information on the next flying object 10 is updated and displayed. In this case, the display control unit 144 causes the display unit 130 to display information based on the first flying object information received at the first time, and displays the information at the second time before the first transmission period elapses. When the communication unit 110 receives the second flying object information at the first time, the display unit displays information based on the first flying object information received at the first time. In this manner, the display control unit 144 preferentially displays the first flying object information on the display unit 130 when the communication unit 110 is normally sequentially receiving the first flying object information.

On the other hand, if the communication unit 110 does not normally receive the first flying object information, the communication unit 110 receives the first flying object information at the first time and then receives the first transmission cycle. After elapses, the next first aircraft information is received. In this way, when the time until the next reception of the first flying object information becomes longer, the communication unit 110 receives the first flying object information at the first time, and then the first transmission period elapses. After that, one second flying object information is received at one second time.

Therefore, the display control unit 144, in response to the judgment unit 143 judging that a predetermined period equal to or longer than the first transmission cycle has passed since the one first time, displays the one second time. Information based on the second aircraft information received at the time is displayed on the display unit 130 . As a result, the display control unit 144 can cause the display unit 130 to display information based on the second aircraft information for which communication failure does not occur when there is a failure in receiving the first aircraft information. . Note that the display control unit 144 displays information based on the second flying object information received at the first second time in response to the judgment unit 143 judging that the difference from the transmission time exceeds the predetermined time difference. You may make it display on the display part 130. FIG.

Here, the display control unit 144 causes the display unit 130 to display information based on the first aircraft information, and the determination unit 143 determines that the second time is a predetermined period from the first time. is determined to have passed, the information based on the first flying object information is updated to the information based on the second flying object information received at the second time and displayed. As a result, the display control unit 144 smoothly switches the information of the flying object 10 from the information based on the first flying object information, which has been preferentially displayed on the display unit 130, to the information based on the second flying object information. can be displayed.

The display control unit 144 may acquire map information via the communication unit 110 and cause the display unit 130 to display the map information together with the information on the aircraft 10 . In this case, the display control unit 144 acquires map information corresponding to the position information of the flying object 10 included in the information section of the flying object 10 .

For example, the determination unit 143 performs the determination operation described above on the information of the second time that the second acquisition unit 142 has acquired in time series, in chronological order. In this case, the display control unit 144 causes the display unit 130 to display information based on the first flying object information or information based on the second flying object information according to the determination result of the determining unit 143 . As a result, the terminal device 100 can continue to display the latest information of the aircraft 10 according to the communication state on the display unit 130 in a simple and prompt manner.

Although an example in which the terminal device 100 according to the present embodiment receives the first flying object information and the second flying object information from one flying object 10 has been described above, the terminal device 100 is not limited to this. The terminal device 100 may receive first flying object information and second flying object information from a plurality of flying objects 10 . In this case, the control unit 140 executes, for example, the determination operation and the display control operation described above for the first flying object information and the second flying object information having the same aircraft identification information. As a result, the terminal device 100 can appropriately handle the information of the plurality of flying objects 10 and display it on the display unit 130 .

<Example of information on the flying object 10>
FIG. 3 shows an example of information about the aircraft 10 displayed on the display unit 130 by the display control unit 144 according to this embodiment. FIG. 3 shows an example in which the display control unit 144 causes the display unit 130 to display information about the aircraft 10 together with map information. For example, when using the first flying object information, the display control unit 144 displays a mark M indicating the flying object 10 at the position of the map information corresponding to the position information of the flying object 10 included in the first flying object information. Let

Further, when the display control unit 144 causes the display unit 130 to display information based on the first aircraft information, the display control unit 144 uses a predetermined display format corresponding to the first communication means and also corresponds to the second communication means. is displayed in a display format different from the predetermined display format. For example, the display control unit 144 causes the mark M indicating the aircraft 10 to be displayed in a color corresponding to the first communication means. Further, the display control unit 144 may display the shape of the mark M indicating the flying object 10 in a shape corresponding to the first communication means.

Similarly, when using the second flying object information, the display control unit 144 places a mark M indicating the flying object 10 at the position of the map information corresponding to the position information of the flying object 10 included in the second flying object information. display. Then, when the display control unit 144 causes the display unit 130 to display information based on the second flying object information, in a predetermined display format corresponding to the second communication means and corresponding to the first communication means Display in a display format different from the predetermined display format.

For example, the display control unit 144 causes the mark M indicating the aircraft 10 to be displayed in a different color from the color corresponding to the first communication means. Further, the display control unit 144 may display the shape of the mark M indicating the flying object 10 in a shape different from the shape corresponding to the first communication means. Thereby, the user of the terminal device 100 can confirm the communication state with the flying object 10 while confirming the position of the flying object 10 .

Note that the display control unit 144 may cause the display unit 130 to display information based on the second flying object information while displaying information based on the first flying object information on the display unit 130 . In this case, the display control unit 144, for example, updates the information based on the first flying object information to the information based on the second flying object information, and changes the predetermined display format corresponding to the first communication means to the second display format. The information based on the second flying object information is displayed on the display unit 130 by updating to a display format predetermined corresponding to the two communication means.

Similarly, the display control unit 144 may cause the display unit 130 to display information based on the first aircraft information while the display unit 130 is displaying information based on the second aircraft information. In this case, the display control unit 144, for example, updates the information based on the second flying object information to the information based on the first flying object information, and changes the predetermined display format corresponding to the second communication means to the first display format. The information based on the first aircraft information is displayed on the display unit 130 by updating to a display format predetermined corresponding to the first communication means.

The display control unit 144 may also cause the display unit 130 to display information on the area where the aircraft 10 is located. FIG. 3 shows an example in which the display unit 130 displays that the area where the aircraft 10 is located is a no-fly zone.

<Example of Operation Flow of Terminal Device 100>
FIG. 4 shows an example of the operation flow of the terminal device 100 according to this embodiment. The operation flow shown in FIG. 4 is an example of an operation flow started when the user of the terminal device 100 executes an application for confirming information on the aircraft 10 and the terminal device 100 and the aircraft 10 communicate with each other. is.

First, the communication unit 110 starts the operation of receiving the first flying object information and the second flying object information (S71). The communication unit 110 repeats the operation of receiving the aircraft information at a predetermined cycle. The communication unit 110 repeats the operation of receiving aircraft information in synchronization with, for example, a clock signal inside the terminal device 100 . In other words, the communication unit 110 starts the operation of waiting for reception of the first flying object information and the second flying object information.

The first acquisition unit 141 operates to acquire the first aircraft information and the information of the first time from the communication unit 110 , and the second acquisition unit 142 operates to acquire the second aircraft information and the information of the second time from the communication unit 110 . It operates so as to acquire information (S72). Accordingly, when the communication unit 110 receives the first flying object information, the first obtaining unit 141 can obtain the first flying object information and the information of the first time. The second acquisition unit 142 can acquire second aircraft information and second time information.

For example, when the communication unit 110 receives the first flying object information, the first obtaining unit 141 obtains the first flying object information and the information on the first time from the communication unit 110 (S73: Yes). In this case, the display control unit 144 causes the display unit 130 to display information based on the first aircraft information acquired by the first acquisition unit 141 (S74).

If the user has not stopped the operation of the application (S78: No), the terminal device 100 returns to S72, and the first acquisition unit 141 and the second acquisition unit 142 cause the communication unit 110 to receive the information on the aircraft 10. Check if you are For example, when the communication unit 110 normally receives the first flying object information but does not normally receive the second flying object information, the terminal device 100 performs the operations of S72, S73, S74, and S78, and S72, The operations of S73, S75, and S78 are alternately repeated. Accordingly, the display control unit 144 causes the display unit 130 to sequentially update and display information based on the first aircraft information.

Here, when the communication unit 110 normally receives the second flying object information, the second obtaining unit 142 obtains the second flying object information and the second time information from the communication unit 110 (S75: Yes). . When the second acquisition unit 142 acquires the second aircraft information from the communication unit 110, the determination unit 143 determines that the second time acquired by the second acquisition unit 142 is earlier than the second time, and It is determined whether or not a predetermined period equal to or longer than the first transmission cycle has passed from the first time closest to the second time (S76).

In response to the determination unit 143 determining that the predetermined period has not elapsed from the first time at the second time (S76: No), the display control unit 144 displays the first aircraft information received at the first time. is displayed on the display unit 130. In this case, the display control unit 144 causes the display unit 130 to display the information based on the first flying object information received at the first time, so that the display unit 130 continues to display the information. become.

If the user has not stopped the operation of the application (S78: No), the terminal device 100 returns to S72. Therefore, for example, when the communication unit 110 normally sequentially receives the first aircraft information and the second aircraft information, the terminal device 100 performs steps S72, S73, S74, and S78 are executed, and when the communication unit 110 receives the second flying object information, the operations of S72, S73, S75, S76, and S78 are executed. Accordingly, the display control unit 144 causes the display unit 130 to update and display information based on the first flying object information each time the communication unit 110 receives the first flying object information.

Note that if the communication unit 110 normally receives the second aircraft information while the communication unit 110 does not normally receive the first aircraft information, the determination unit 143 determines in S76 that the second time is a predetermined time from the first time. period has elapsed (S76: Yes). In this case, the display control unit 144 causes the display unit 130 to display information based on the second aircraft information received at the second time (S77). As a result, the display control unit 144 can switch the information based on the first aircraft information, which has been preferentially displayed on the display unit 130 , to the information based on the second aircraft information, and display the information on the display unit 130 .

If the user has not stopped the operation of the application (S78: No), the terminal device 100 returns to S72. Therefore, for example, when the communication unit 110 receives the second flying object information normally without being able to receive the first flying object information, the display control unit 144 controls the display control unit 144 every time the communication unit 110 receives the second flying object information Information based on the second aircraft information is updated and displayed on the display unit 130 .

Here, when the communication unit 110 receives the first flying object information, the terminal device 100 executes the operations of S72, S73, S74, and S78 when the communication unit 110 receives the first flying object information. As a result, the display control unit 144 updates the information based on the second flying object information displayed on the display unit 130 to the information based on the first flying object information and displays it.

If the communication unit 110 has not received the first flying object information and the second flying object information (S73: No, S75: No), the process returns to S72 via S78. In other words, if the user has not stopped the operation of the application (S78: No), the terminal device 100 repeats the operations of S72, S73, S75, and S78 to obtain the first aircraft information and the second aircraft information. Waiting for reception.

Here, if the communication unit 110 fails to receive the first flying object information and the second flying object information even after a predetermined time has passed, the display control unit 144 displays on the display unit 130 that the communication state is bad. It is desirable to Also, when the user stops the operation of the application (S78: Yes), the terminal device 100 stops the processing of the application. By executing the operation flow from S71 to S78, the terminal device 100 according to the present embodiment described above appropriately responds to the communication unit 110 receiving the first flying object information and/or the second flying object information. Such information of the flying object 10 can be displayed on the display unit 130 .

In the terminal device 100 according to the present embodiment described above, the terminal device 100 displays the received information about the flying object 10 on the display unit 130 based on the time when the communication unit 110 receives the information about the flying object 10. Although an example has been described, it is not limited to this. The terminal device 100 preferentially displays information based on the first flying object information on the display unit 130 on condition that the signal strength of the first flying object information received by the communication unit 110 exceeds the threshold. good.

In this case, the determination unit 143 determines whether or not the signal strength of the first flying object information received at the one first time exceeds the threshold, and whether or not the one second time has passed a predetermined period from the one first time. determine whether or not Then, the display control unit 144 determines that the signal strength of the first flying object information exceeds the threshold and that the one second time has not passed the predetermined period from the one first time. In accordance with the determination, the display unit 130 is caused to display information based on the first aircraft information received at the first time.

For example, in the operation flow of FIG. 4, even if the first acquiring unit 141 acquires the first flying object information in S73 (S73: Yes), the determining unit 143 determines that the signal strength of the first flying object information exceeds the threshold. Determine whether or not it exceeds Then, if the determination unit 143 determines that the signal strength of the first flying object information does not exceed the threshold, the display control unit 144 does not display information based on the first flying object information, and proceeds to S78.

Then, when the signal strength of the first flying object information continues to be less than the threshold and the communication unit 110 receives the second flying object information (S75: Yes), the determination unit 143 has elapsed (S76: Yes), and the display control unit 144 causes the display unit 130 to display information based on the second aircraft information (S77).

Further, when the communication unit 110 receives the first flying object information (S73: Yes) and the signal strength of the first flying object information has recovered to the abnormal threshold value, the display control unit 144 displays the first flying object information. Based information is displayed on the display unit 130 (S74). Then, when the communication unit 110 receives the second flying object information (S75: Yes), the determination unit 143 determines that the predetermined period has not passed since the first time (S76: No), and the display control unit 144 continues the state in which information based on the first aircraft information is displayed on the display unit 130 .

In addition, in the determination operation of S76 in the operation flow of FIG. 4, after determining that the predetermined period has not elapsed from the first time, the determination unit 143 determines that the signal strength of the first flying object information received at the first time is exceeds a threshold. Then, when the determination unit 143 determines that the signal strength of the first flying object information does not exceed the threshold, the display control unit 144 moves to S77 to display the second flying object received at the second time. Information based on the information is displayed on the display unit 130 . As a result, the terminal device 100 can cause the display unit 130 to display information based on the second flying object information when the signal strength of the first flying object information is lower than the threshold.

Therefore, when the signal strength of the first flying object information does not exceed the threshold, the terminal device 100 can preferentially display the information based on the second flying object information on the display unit 130 . When the terminal device 100 determines that the signal strength of the first flying object information exceeds the threshold value, the terminal device 100 preferentially displays the information based on the first flying object information on the display unit 130 as described above. display.
