FIG. 1 is a schematic view of a multi-satellite operating system according to an embodiment of the present invention. Referring to FIG. Referring to FIG. 1, a multi-satellite operating system includes multiple satellites 100, an image receiving antenna 200, a receiving / demodulating module 300, a photographing planning sub module 400, an integrated receiving module 500, Module 600 as shown in FIG.

Multiple satellites (100) comprising at least one satellite (101, 102, 103) can revolve around the earth and acquire image data. Each of the multiple satellites 100 is equipped with a mission payload such as an optical camera, a radio wave camera, an infrared camera, or a multispectral camera according to the purpose. Using the satellite image information acquired through the mission payload, Detection, cloud movement, weather conditions, ocean or ocean environmental changes, etc., to monitor or predict changes. The image information acquired by each of the multiple satellites 100 may be transmitted to the reception / demodulation module 300 through the image reception antenna 200 and demodulated.

Module 400 may generate a radiographing plan that allows orbits to propagate and determines when each of the multiple satellites 100 should capture an order region when a video imaging order is input from a user. Module 400 may generate a product generation report related to the mission timeline and the imaging order / processing request based on the imaging plan.

The integrated receiving module 500 may integrate the task schedule and task contents of each of the multiple satellites 100 so as to avoid conflicts based on the task schedule for each of the multiple satellites 100 received from the shot scheduling sub- An integrated work order can be created. The integrated receiving module 500 may process the image information received from the receiving / demodulating module 300 based on the integrated work instruction sheet to generate first image information for each of the multiple satellites including the satellite image and the auxiliary information.

FIG. 2 is a diagram for explaining a detailed configuration of the integrated receiving module 500 among the multiple satellite operating systems of FIG. Referring to FIG. 2, the integrated reception module 500 includes an integrated work instruction generator 510, a database 520, an integrated reception controller 530, a reception card 540, an integrated reception preprocessor 550, (560). ≪ / RTI >

The integrated work instruction sheet generating unit 510 checks whether the format of the mission time table file for each of the multiple satellites 100 received from the imaging plan submodule 400 is normal and displays the work instruction contents of each of the multiple satellites 100 You can create an integrated work order. Here, the contents of the mission timetable file include information such as the satellite ID, tasks performed by the satellite by time, task performed by the payload unit, time available for receiving, start time of receiving equipment, transmission time of satellite, ground station ID, , The mission timetable file is automatically stored in a specific folder, and the format of the mission timetable file can be ASCII code. The contents of the mission timetable file may be different for each of the multiple satellites 100 because the performance and characteristics of the payload are different for each of the multiple satellites 100. Operators operate satellite / payload / terrestrial systems specially according to the contents of different mission timetables for each of the multiple satellites 100.

The integrated work instruction sheet generating unit 510 periodically polls the folder storing the task time schedule file created in the ASCII code format and extracts the satellite information from the task time schedule file, You can identify and categorize. The integrated work instruction sheet generating unit 510 may classify the satellites, generate a work order for each satellite, and integrate the work instruction sheets for each satellite. The integrated work instruction sheet generating unit 510 may generate an integrated work instruction sheet so that multiple tasks for each satellite are not simultaneously performed on one apparatus when the work instruction sheets for each satellite are integrated. The mission timetable can be used to represent the tasks performed by human-made time / satellites / payloads / terrestrial systems. The work instructions are based on the mission timetable and automatically applied to flight operations rules, ground system operation rules, Work instructions can be shown. The integrated work instruction sheet generating unit 510 may transmit the generated integrated work instruction sheet to the integrated reception control unit 530.

The integrated work instruction sheet generation unit 510 may integrate the contents of the mission time tables of each of the multiple satellites 100 so as to prevent a collision between the work time sequence and the task contents. At this time, it is possible to prevent the collision using the database 520 in which the previously created work instruction sheet is stored. In addition, the database 520 may register the failure of various equipments and the use of surplus resources to prevent collision and increase the efficiency. If the integrated work instruction sheet generating unit 510 fails to generate an integrated work instruction sheet, a report can be generated and informed to the user.

The video reception plan included in the integrated work instruction sheet generated by the integrated work instruction sheet generation unit 510 may be created on a weekly or daily basis. However, when a disaster disaster or an urgent image capturing request occurs, an emergency image receiving plan should be created and performed. Conventionally, when an urgent reception request is made for each satellite, this is manually performed. However, since the integrated reception module 500 has a function of automatically processing and checking whether there is a collision, an emergency reception plan can be automatically generated . To this end, the reception monitoring unit 560 monitors the reception of the emergency image reception request signal from the user, notifies the integrated reception control unit 530 of the reception of the emergency image reception request signal, and the integrated operation instruction form generation unit 510, under the control of the integrated reception control unit 530, The previous integrated work instruction sheet can be canceled and a new integrated work instruction sheet reflecting the urgent image reception plan can be generated.

Since the integrated work instruction sheet generating unit 510 automatically generates the tasks of the image receiving antenna 200, the reception / demodulation module 300, and the integrated reception module 500 by satellite and by time without collision, It is possible to inquire of the database 520 whether there is a work instruction sheet and replace it with a newly created integrated work instruction sheet for emergency operation. Since the integrated work instruction sheet generation process for integrating the different task satellite directives without collision after the work instruction sheet generation process for each of the multiple satellites 100 is separately provided, the integrated reception module 500 may be added even if the new satellite preprocessor 554 is added. Can be performed without change.

The integrated reception controller 530 may operate the reception card 540 and the integrated reception preprocessor 550 before a specific reception start time based on the integrated work instruction from the integrated work instruction generator 510. [

The reception card 540 is a hardware card developed in a VHDL (VHSIC hardware description language) scheme. The reception card 540 receives image information from a satellite in a bit stream format at each reception time of the multiple satellites 100, and performs frame synchronization, descrambling de-scrambling, and reed-solomon decoding operations. The integrated work instruction sheet generated by the integrated work instruction sheet generating unit 510 may include a first data reception card 541 and a second data reception card 541, The first signal processing of all the multiple satellites 100 can be performed with only two receiving cards composed of the card 542. [ In this embodiment, the receiving card 540 includes a first data receiving card 541 for receiving a left hand circuit polarization (LHCP) polarization and a second data receiving card 542 for receiving a right hand circuit polarization (RHCP) And can receive image information from each of the multiple satellites 100 using the first data receiving card 541 and the second data receiving card 542. [ Data on which the frame synchronization, descrambling, and Reed-Solomon decoding operations on the receiving card 540 have been completed can be referred to as transfer frame data as the first signal processing result information.

The integrated reception preprocessing processor 550 receives the transmission frame data for each of the multiple satellites 100 from the reception card 540 and performs processing such as missing data processing, decryption, transfer frame merging, And generate first image information, that is, source packet data including a satellite image and auxiliary information as a result of the second signal processing. Here, the first image information, that is, the source packet data may be referred to as Level OF data, and the image data obtained by decoding, decrypting, and decompressing the data received from the satellite may be referred to as bitstream. Conventional preprocessing processors require individual equipment for each satellite. That is, the first satellite (for example, the multipurpose satellite 2) is the first satellite preprocessor, the second satellite (for example, multipurpose satellite 3) is the equipment for the second satellite preprocessing processor, (For example, multipurpose satellite 5), equipment for the third satellite preprocessing processor, and satellite 4 (for example, multipurpose satellite 6) required equipment for the fourth satellite preprocessing processor. However, in the present embodiment, the integrated reception pre-processing processor 550 can be operated in one equipment. That is, the operations of the first satellite preprocessing processor 551 to the new satellite preprocessing processor 554 can be operated on one equipment, that is, one workstation, thereby reducing the number of equipment.

The reception monitoring unit 560 may monitor the information reception status of the integrated reception module 500 and transmit the result to the integrated reception control unit 530. [ In particular, the reception monitoring unit 560 may monitor the reception of the emergency image reception request signal from the user and transmit the monitoring result to the integrated reception control unit 530.

Referring back to FIG. 1, the integrated processing module 600 receives an integrated product management work instruction sheet that incorporates a product management work instruction sheet based on a product generation report for each of the multiple satellites 100 received from the imaging plan sub module 400 Satellite-based first image information received from the integrated receiving module 500 to a plurality of virtual machine-level processors that are load-balanced through resource control, And generate the second to fourth image information for each of the multiple satellites as a result.

FIG. 3 is a view for explaining a detailed configuration of the integrated processing module 600 among the multiple satellite operating systems of FIG. Referring to FIG. 3, the integrated processing module 600 may include an integrated product management sub-module 610 and a virtual machine-based level processor 620. The integration processing module 600 receives a product creation report containing information on how to process the first image information (Level OF data) of each of the multiple satellites 100 from the imaging plan submodule 400, (Level OF data) of each of the multiple satellites received from the first satellite and the product creation report.

The integrated product management submodule 610 receives first image information (Level OF data) of each of the multiple satellites 100 from the integrated receiving module 500 and outputs first image information (Level OF data) To the virtual machine-based level processor 620. In this embodiment, the integrated product management submodule 610 may include an integrated product management work instruction booklet generation unit 611, a virtual machine resource monitoring unit 612, and a virtual machine resource control unit 613.

The integrated product management work instruction creation unit 611 checks whether the format of the product creation report file for each of the multiple satellites 100 received from the imaging plan submodule 400 is normal, You can create an integrated product management work order that incorporates management work order instructions. Here, the contents of the product creation report include satellite name, video order ID, name of product storage folder per satellite, type of product (Level 1R or Level 1G), video product ID, product requester information, Time, product creation deadline, and so on. The format of the product creation report file is XML code. The contents of the product creation report file may be different for each of the multiple satellites 100 because the product form, the captured image area, the product request date and time, and the product creation deadline differ depending on the product requester.

The integrated product management work instruction book generation unit 611 periodically polls the folder storing the product creation report file created in the XML code format to read the product creation report file and then classify the contents of the product creation report by satellite have. The integrated product management work instruction book generation unit 611 may classify the satellites, generate a product management work instruction sheet for each satellite, and integrate the product management work instruction manual for each satellite. The integrated product management work instruction sheet generating unit 611 may generate an integrated product management work instruction sheet so that multiple tasks for each satellite are not simultaneously performed in one apparatus when the product management task instruction for each satellite is integrated.

The integrated product management work instruction sheet generating unit 611 may integrate the contents of the product management work instruction sheets of each of the multiple satellites 100 so that conflicts between the time order and the task contents between the tasks do not occur. The integrated work instruction sheet generation unit 510 of the integrated reception module 500 should be able to prepare an integrated work instruction sheet so that the satellite must be received when the satellite passes over the ground base and notify the success and failure of the preparation. In comparison with this, the integrated product management work instruction booklet generator 611 of the integrated product management sub-module 610 creates an integrated product management work instruction booklet so that the integrated product management work instruction booklet is processed at different times according to the contents of the request for each product requester and the priority order of requests And be able to tell the time required to create the product.

The virtual machine resource monitoring unit 612 monitors the virtual machine resources of the virtual machine based level processor 620, that is, the level processors LP (Level Processors, VM # 1 to VM # 12) included in the virtual machine based level processor 620, Monitor CPU usage, memory usage, and the like, and transmit the monitoring result to the virtual machine resource control unit 613.

The virtual machine resource control unit 613 can control the CPU usage and the memory usage of each level processor transmitted from the virtual machine resource monitoring unit 612 to perform efficient image processing. Load balancing of the level processors is achieved through virtual machine resource monitoring and virtual machine resource control.

Because each of the multiple satellites 100 has different image processing logic depending on payload characteristics, the functionality and performance of each of the level processors included in the virtual machine based level processor 620 may vary from satellite to satellite. The virtual machine resource control unit 613 allocates a large amount of resources to the first satellite level processors VM # 1, VM # 5, and VM # 9 during the first satellite image processing, The efficiency can be increased by allocating the minimum resources to the processors (VM # 2 to VM # 4, VM # 6 to VM # 8, VM # 10 to VM # 12).

The integrated product management submodule 610 allocates resources under the control of the virtual machine resource control unit 613 to acquire first image information (Level OF data) of each of the multiple satellites 100 received from the integrated receiving module 500 The second image to the fourth image can be generated. In accordance with the rules of the integrated product management work instruction generator 611, the virtual machine resource control unit 613 divides the first image information (Level OF data) and outputs the level information included in the virtual machine based level processor 620 And sends the resultant processed by each level processor included in the virtual machine-based level processor 620 to the virtual machine resource control unit 613. The virtual machine resource control unit 613 can transmit the first image information (Level OF data) located next to the previously divided portion to the empty level processor after the processing is completed. This method can be repeated to complete the image processing of the entire first image information (Level OF data).

Each of the level processors included in the virtual machine-based level processor 620 has the same function of processing an image, and the reason for processing an image with a plurality of level processors is to satisfy the image processing completion time required by the satellite.

The virtual machine-based level processor 620 may perform image processing including radiation correction and geometry correction. Here, the radiation correction may include correcting the radiation distortion appearing in the image by the unique characteristic of each satellite. Radiation distortion can be caused by the pixel-by-pixel and band-specific characteristics of a charge coupled device, or by a change in characteristics as a result of aging of the charge coupled device. It is possible to correct the radiation distortion by performing the optical correction using the values obtained through the pre-launch test and the values obtained using the specific correction site during the post-launch operation. The geometric correction may also include correction of the geometric distortion of the image due to satellites' position and orientation, speed variation, scan range, scan speed, and earth rotation.

The virtual machine based level processor 620 performs copy correction and geometric correction on the first image information (Level OF data) of each of the multiple satellites 100 received from the integrated receiving module 500 to generate second image information (Level 1A ), Third image information (Level 1R), and fourth image information (Level 1G). Here, the second image information (Level 1A) is a result of combining the images in each observation wavelength band using the first image information (Level OF data) or performing a partial correction operation, and is a bit stream type. The third image information (Level 1R) is a result of performing the radiation correction using the second image information (Level 1A), and is a scene form. Also, the fourth image information (Level 1G) is a result of performing geometric correction using the third image information (Level 1R), and the image mapped to the map is output and is in the form of a scene.

In this embodiment, at the same time as the load balancing application, reflecting the operation concept of the low-earth orbit satellite may be a core of hardware reduction. Earth orbit satellites other than geostationary satellites communicate with each other only at a specific time due to their trajectory characteristics. In the case of the multipurpose satellite series, the orbits of the satellites are different from each other. At this time, the main content of the operation method of the integrated processing module 600 may be to prevent the reception task from being collided.

3, the integrated product management submodule 610 performs product management of multiple satellites 100 in one device, rather than performing product management for one satellite in one device, And the virtual machine-based level processor 620 that performs image processing also allows the three devices to perform image processing on one satellite, and three devices to perform image processing on the multiple satellites 100 in an integrated manner The number of equipment required can be reduced.

FIG. 4 is a flowchart illustrating an operation method of the integrated receiving module 500 among the multiple satellite operating systems of FIG.

In step S411, the integrated receiving module 500 determines whether the format of the mission time table file for each of the multiple satellites 100 generated in the ASCII code format received from the imaging plan submodule 400 is normal.

In step S413, when the format of the mission time table file is abnormal, the integrated receiving module 500 outputs an error message and terminates.

If the format of the mission time schedule file is normal in step S415, the integrated reception module 500 classifies the satellite corresponding to the mission time schedule file.

In step S417, the integrated receiving module 500 generates a classified work order for each satellite. A first satellite work instruction sheet, a second satellite work instruction sheet, a third satellite work instruction sheet, and a fourth satellite work instruction sheet when the satellite classified as the embodiment is the first satellite to the fourth satellite.

In step S419. The integrated receiving module 500 generates an integrated work instruction sheet that integrates the classified work order of each satellite. Here, the integrated receiving module 500 may generate an integrated work instruction sheet so that multiple tasks for each satellite are not simultaneously performed on one device at the time of incorporating work instructions for each satellite, that is, have. The integrated receiving module 500 can prevent the collision using the database in which the work instruction sheet prepared previously is stored. The integrated receiving module 500 may generate a report to inform the user if the integrated work instruction book creation fails.

In step S421, the integrated receiving module 500 determines whether there is an urgent video reception plan request from the user.

In step S423, if there is an urgent video reception plan request, the integrated reception module 500 cancels the previous integrated work instruction stored in the database.

In step S425, the integrated receiving module 500 generates a new integrated work instruction sheet reflecting the emergency image reception plan after canceling the previous integrated work instruction sheet, and registers the new integrated work instruction sheet in the database. If there is no urgent video reception plan request, the integrated reception module 500 registers the integrated work instruction sheet generated in step S419 in the database.
