In FIG. 4, reference numeral 1 denotes a GP which receives a signal from a satellite and displays a place on the earth based on position information of latitude, longitude and altitude.
The GPS receiving unit 1 is an S (Global Positioning System) receiving unit. The GPS receiving unit 1 amplifies a very weak signal output from the antenna 1a that receives signals from satellites and a frequency that is easy to handle. The receiving unit 1b for conversion and the signal processing unit 1c for calculating the position information of the current position based on the signal output from the receiving unit 1b. The position information processed by the GPS receiving unit 1 is displayed on the display unit 2 as time, latitude, and latitude information. The setting change such as the standard time setting among the positions and time data displayed on the display unit 2 is performed by inputting from the input unit 3. As described above, the current position and the like can be known from the position display device.

[0004]

However, in such a conventional configuration, although the position information displayed on the display unit 2 can be recognized as longitude, latitude and altitude, it is difficult to intuitively understand as it is. Therefore, when using mobile communication, if you want to inform the other party of the communication of the operating point of your own station, or conversely if you want to know the operating point of the other party, based on the longitude and latitude Was checked with reference to a map and the like, and the current position was popped out and converted into a grid locator number to inform it. The grid locator number is a division of the earth's surface into blocks with a longitude of 5 minutes and a latitude of 2.5 minutes, based on a point of longitude 0 ° and latitude 0 °, two alphabets, and then two Arabic numerals. It is displayed again with a total of 6 letters, which is 2 letters of the alphabet. Using the grid locator number makes it easy to see his positional relationship as if he were laying a go stone on the board, but the task of converting to this grid locator number is troublesome. It was

[0007]

With this configuration, among the position information from the GPS receiving unit, the longitude and latitude information is automatically converted into the grid locator number and displayed on the display unit.

[0008]

Embodiments of the present invention will now be described with reference to the drawings. The same parts as those of the conventional example are designated by the same reference numerals and duplicate description will be omitted.

FIG. 1 is a block diagram of a position display device according to one embodiment of the present invention, FIG. 2 is a display example of the display section in FIG. 1, and FIG. 3 is a more detailed display example of the display section in FIG. .

First, the outline of the present invention will be described with reference to FIG. In FIG. 1, of the longitude, latitude, and altitude position information received from the GPS receiving unit 1, the control unit 4 transmits the longitude and latitude information to the conversion unit 5. When the role of the conversion unit 5 is applied to the conventional example, it corresponds to a user who is playing a grid locator number with a map in one hand, and the conversion unit 5 receives the longitude and latitude received from the control unit 4. Automatically convert to grid locator number information based on the information. The control unit 4 reads the information of the grid locator number converted by the conversion unit 5, and displays it on the display unit 2 together with the position information and other information obtained from the GPS receiving unit 1. Here, regarding the longitude and latitude information that the control unit 4 receives from the GPS receiving unit 1, the position information of its own automatically measured based on the signal from the satellite and the other party of the mobile communication are instructed, There are two types, that is, the position information of the other party measured by inputting from the input unit 3, and in either case, the conversion unit 5 promptly outputs the grid locator number.

The operation of the position display device of the present invention will be described in detail below with reference to FIGS. 2 and 3 in addition to FIG.

Of the various information in the display example shown in FIG. 2, the "destination", "used frequency", "call code", etc.
Input is performed using a keyboard as an example, but in the "used frequency", if the input unit 3 is provided with a frequency counter unit that counts high frequency signals, it can be automatically displayed. In addition, "Grid Locator Number", "Latitude", "Longitude", "Date", "Japan Time", "World Standard Time", etc. are automatically displayed. In general, in international communication experiments, the world standard time is used rather than Japan time to record in the business diary, so the world standard time is also displayed.

FIG. 3 shows detailed information such as the relative azimuth between the own station and the partner station, the ground distance, and the like. Each grid-shaped block shown in FIG. 3 is one grid locator, and as described above, this grid locator has a longitude of 5 minutes with respect to the earth's surface at zero degrees longitude and latitude zero degrees. It is divided into blocks each having a pitch of 2.5 minutes. The grid locator number is obtained by associating each of these blocks with two letters of the alphabet, two letters of the Arabic numeral, and two letters of the alphabet again, for a total of six letters. Such a graphic display makes it much easier to intuitively understand the positional relationship between the own station “PM53CG” and the partner station “PM53FK” based on the longitude and latitude information in the case of displaying characters.

By the way, the position determined by the longitude and latitude is one point, but since the position display by the grid locator number is the display of the area of one block, the current position is within the area of the block. I don't know where it is. In other words, it is unknown whether it is closer to the center or closer to the edge. To supplement this point, if the center point in the area of the block is regarded as the position of 50% in the longitude and latitude directions, for example, the block of "PM53CG" In the area, the longitude and latitude information shown in FIG. 2 can be displayed as one point on the display surfaces of “90% to the east”, “90% to the north” and “PM53CG”, respectively.

[0015]

The position display device of the present invention receives the position information from the GPS receiving section which measures the position based on the signal from the satellite and the GPS receiving section through the control section and converts it into the grid locator number. A conversion unit, a control unit for displaying the grid locator number converted by the conversion unit, and other information on the display unit, and an input unit for inputting various information to the GPS reception unit were provided.

With this configuration, among the position information from the GPS receiving unit, the longitude and latitude information is automatically converted into the grid locator number and displayed on the display unit, and the position information from the communication partner is input. By inputting from the department, the grid locator number of the other party can be quickly converted and displayed. As a result, it is possible to save time and effort by referring to a map or the like based on the longitude and latitude information to find out the current position and convert it into a grid locator number.
