[0035] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments disclosed in the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] The present application embodiment discloses a remote sensing satellite proximity search subsystem test system and method, such as Figure 1 As shown, it includes: satellite platform and ground test system.

[0037] The ground test system consists of a server, a master control system, and interpretation and analysis software. Users send remote control commands through the master control system and obtain telemetry information on the satellite to complete the control of the satellite equipment and status monitoring; the interpretation and analysis software is used to complete the analysis and interpretation of the information. Information exchange is achieved between the satellite and the ground through the server and the integrated electronic subsystem. The information exchange diagram is shown in the figure below. Figure 1 shown.

[0038] Specifically, the master control system sends a remote control command to the server, obtains on-board telemetry information and on-board data from the server, and sends the on-board telemetry information and on-board data to the interpretation and analysis software;

[0039] Interpretation and analysis software, receiving on-board telemetry information and on-board data from the master control system, and analyzing and interpreting the on-board telemetry information and on-board data;

[0040] The server sends the remote control command to the integrated electronic subsystem and obtains the on-board telemetry information and on-board data from the integrated electronic subsystem.

[0041] The satellite platform includes an on-board integrated electronic subsystem and a power distributor. The integrated electronic subsystem receives remote control commands and sends them to the target camera and two-dimensional turntable of the proximity search subsystem, and receives on-board telemetry information and on-board data from the proximity search subsystem. The power distributor is used to supply power to the proximity search subsystem and the integrated electronic subsystem.

[0042] The remote sensing satellite proximity search subsystem consists of a target camera and a two-dimensional turntable, generally including two or more groups of target cameras and turntables. The subsystem communicates with the onboard integrated electronic subsystem via the Spacewire bus, 1553B bus and RS422. Specifically, the target camera and the two-dimensional turntable set their status according to the remote control command, and feed back the onboard telemetry information and onboard data to the integrated electronic subsystem; the two-dimensional turntable is responsible for powering the target camera, and the two-dimensional turntable drives the target camera to rotate by rotating itself.

[0043] The remote sensing satellite proximity search subsystem test generally includes power supply interface inspection, remote control telemetry and bus interface inspection, pulse-per-second interface inspection and mode test. The mode test includes self-test mode test, standby mode test, positioning mode test and mission mode test. The remote sensing satellite proximity search subsystem test process is as follows: Figure 2 As shown, the test process sequence generally cannot be changed and must be performed in this sequence.

[0044] The test process is as follows:

[0045] Step 1: Check the power supply interface: The power supply interface check generally requires inserting a transfer box in series at the end of the equipment cable to measure its static resistance; after the entire satellite is powered on (both the satellite platform and the proximity search subsystem are powered on), measure its power supply input voltage. The power supply interface check is a prerequisite test item to ensure the normal operation of the system, and must be performed first.

[0046] Step 2: Remote control, telemetry and bus interface inspection: The remote control, telemetry and bus interface inspection needs to be carried out when the whole satellite is powered on. The test personnel need to first send the proximity search subsystem power-on command through the master control system to check the initial telemetry information; then send the subsystem related commands, which include: commands to make the proximity search subsystem move, information flow, data interaction and / or self-check, check the increase of the subsystem remote control command count; check the bus monitor bus data, and check the bus interface status.

[0047] Step 3: Second pulse interface check: The second pulse interface check needs to be tested when the entire satellite and subsystems are powered on. The tester injects the second pulse timing instruction into the main control system to check the timing status of the proximity search subsystem and the difference Δt between the proximity search subsystem time and the entire satellite time.

[0048] Step 4: Self-test mode test: The self-test mode needs to be tested when the entire satellite and subsystems are powered on. The tester injects the subsystem self-test mode command into the main control system, observes the rotation direction of the proximity search subsystem camera, and determines the maximum rotation angle and maximum angular velocity.

[0049] Step 5: Standby mode test: The standby mode needs to be tested when the entire satellite and subsystems are powered on. The tester injects the subsystem standby mode command into the master control system, observes whether the target camera of the proximity search subsystem is rotating, and counts the output image frame count.

[0050] Step 6: Positioning mode test: The standby mode needs to be tested when the whole satellite and subsystems are powered on. The tester injects instructions for the subsystem positioning mode into the master control system and observes whether the target camera of the nearby search subsystem rotates. Generally, the target camera will be rotated to the limit of the four directions to test its positioning function.

[0051] Step 7: Mission mode test: The mission mode needs to be tested when the entire satellite and subsystems are powered on. At the same time, a simulation source needs to be installed on the target camera of the proximity search subsystem. The simulation source is used to simulate the actual image observed by the target camera in orbit. The simulation source generates and simulates the real space environment in real time, and sends the image data of the real space environment to the proximity search subsystem; the proximity search subsystem obtains the image data of the simulation source. The mission mode needs to simulate the on-orbit flight status to the master control system, determine the satellite position and the equatorial distance data in real time, and start up autonomously at a specific distance, complete the task transfer between the target cameras, and finally complete the task and image information download. The tester needs to judge the correctness of the image data after the image is downloaded.

[0052] The interpretation and analysis software realizes the interpretation of the correctness of the task image information. The task image information is recorded in the E-PDU format, and its structure is as follows: Figure 3 As shown. The interpretation and analysis software will perform three-level checks on the image data. First, check whether the packet sequence count of the downloaded image data packet is continuous, then check whether the target camera pitch angle and yaw angle in the E-PDU data field are consistent with the expected, and finally check whether the cumulative checksum in the E-PDU data field is correct. The information in the data field is shown in the following table.

[0054] Example 1

[0055] A test method for a remote sensing satellite proximity search subsystem test system is as follows:

[0056] 1. Check the power supply interface: disconnect Figure 4 Connect the power supply interface X01 in the middle and connect it in series to the adapter box. Use a multimeter to measure its static resistance. After the entire satellite is powered on, use a multimeter to measure its power supply input voltage.

[0057] 2. Remote control, telemetry and bus interface inspection: The tester first sends the proximity search subsystem power-on command T001 through the master control system to check the subsystem voltage analog quantity, that is, after the system is powered on

[0058] F000=U

[0059] The general U needs to meet the following conditions:

[0060] U min ≤U≤U max

[0061] Among them, U min , U max They are the normal minimum and maximum voltages of the system respectively.

[0062] Then, the subsystem command self-check command T002 is sent to check whether the subsystem remote control command count F002 increases by 1 count;

[0063] Finally, turn on the bus monitor device and check whether the transmission cycle and data format of the bus monitor bus data meet the specifications.

[0064] 3. Second pulse interface inspection: The tester enters the second pulse time calibration instruction T003, checks the subsystem time calibration status F004 and the difference between the subsystem time and the whole satellite time F005. The general requirements are:

[0065] F004=1

[0066] F005≤0.0001s

[0067] Among them, F004=1 indicates the state of autonomous time calibration of second pulse.

[0068] 4. Self-check mode test: The tester enters the subsystem self-check mode instruction T005, observes the rotation direction of the target camera of the proximity search subsystem, and interprets the target camera pitch angle F006, target camera yaw angle F007 and maximum angular velocity F008. The general requirements are:

[0069] φ min ≤F006≤φmax

[0070]

[0071] F007≤β max

[0072] Among them, φ min ,φ max Indicates the minimum and maximum rotation angles of the target camera in the pitch direction, usually -90° and 90°; Indicates the minimum and maximum rotation angles of the target camera in the yaw direction, usually -170° and 60°; β max Indicates the maximum angular velocity of rotation, generally 4° / s.

[0073] 5. Standby mode test: The tester notes the subsystem standby mode instruction T006, observes the proximity search subsystem target camera to remain still, and interprets the output image frame count F010. Since it is in standby mode, the image frame count should not increase, which can be expressed as:

[0074] F010=0

[0075] 6. Positioning mode test: The tester injects the positioning mode command T007 into the injection subsystem, and observes whether the target camera of the proximity search subsystem rotates. Generally, the target camera is rotated to the limit of four directions to test its positioning function. Taking the general value of the 4 self-check mode test as an example, the general injection command is as follows:

[0076] T007(-90,-170)

[0077] T007(-90,60)

[0078] T007(90,60)

[0079] T007(90,-170)

[0080] The parameters in brackets represent the pitch angle and yaw angle of the target camera. After the above command is successful, you need to observe whether the target camera rotates to the specified position. After it is fully rotated, send and verify the next command.

[0081] 7. Mission mode test: disconnect Figure 4 The target camera T1 interface shown in the figure is connected to the image simulation source device. The image simulation source can simulate the actual image observed by the target camera in space to meet the needs of ground testing. Then, the task instruction T015 is added. The target camera will determine the distance between the satellite position and the equatorial plane in real time according to the current state of the satellite, and start up autonomously at a specific distance. That is, after determining the distance meets the conditions, whether the device voltage analog quantity changes from 0 to U.

[0082] The system will then complete the self-check autonomously, that is, it will interpret according to the interpretation requirements of this chapter (4. Self-check mode). After completing the self-check, the target camera will follow autonomously, and after completion, the target camera task will be transferred, that is, target camera a will enter the standby mode, and target camera b will enter the task mode. After the task transfer is completed, the system will transmit the task and image information, and the tester will interpret the correctness of the image data.

[0083] The interpretation and analysis software realizes the interpretation of the correctness of the task image information. The task image information is recorded in the E-PDU format, and its structure is as follows: Figure 3 As shown. The interpretation and analysis software will perform three-level checks on the image data. First, it checks whether the packet sequence count of the downloaded image data packet is continuous. Secondly, it checks whether the target camera pitch angle and yaw angle in the E-PDU data field are consistent with the expected ones. Finally, it checks whether the accumulated checksum in the E-PDU data field is correct.
