Problems solved by technology

There are strict order and time interval requirements between commands in the sequence, and the user's on-orbit use and task planning are cumbersome, which brings inconvenience to the data transmission system test and on-orbit use, and the interaction with users is not friendly enough
At the same time, the signal flow direction of the radio frequency channel of the digital transmission system is switched and used through two sets of switches to control the flow direction of the data. In order to realize the correct control of the data flow direction, the number of device combinations is complex, which brings inconvenience to the user, and the operation control is easy to use. sexual insufficiency

Embodiment Construction

[0032] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0033] Table 1 Geolocation task instruction block description

[0034]

[0035] Table 2 Description of target type task instruction block

[0036]

[0037]

[0038] Table 3 Description of target type + geographic location task instruction block

[0039]

[0040] Such as Figure 1~3 And 8, and shown in table 1,2,3, the inventive method specifically comprises the steps:

[0041] (1) The agile satellite mission system receives the uplink task block command from the ground user, and judges the W0 and W1 bytes of the task command in real time. If it is an A5A5H command block, enter step (2); if it is a C3C3H command block, enter Step (3); if it is an AACCH instruction block, then enter step (4);

[0042] (2) Read W2-W13 bytes, the latitude and longitude coordinates of the geographical location area, that is, position 1 point (longitud...

Abstract

The invention relates to a design method for an agile satellite task trigger mode instruction, and belongs to the technical field of agile imaging satellites. Aiming at the on-orbit working characteristics of agile satellites, the invention takes user task triggering as an entry point, and the satellite performs autonomous task planning according to the user task requirements, and feedbacks the planning results to the user in time, so that the user can formulate a reasonable data receiving plan. The tasks that the user puts on the satellite include position task, target type task, and target type + position task. The user only needs to meet the task level requirements such as position and target type, and does not need to arrange instructions, and does not need to know the design principles of satellites and the systems of satellites. The use of constraints simplifies the use of satellites, and finally enables agile satellites to perform on-orbit tasks autonomously.

Description

technical field [0001] The invention relates to an agile satellite task trigger mode instruction design method, which is especially suitable for agile tasks such as large-scale satellites, fast attitude maneuvers, large number of images in one track, and short time. Background technique [0002] The on-board data transmission system is one of the multiple systems of the satellite, and its function is to complete the processing and transmission of the data obtained by the satellite payload. The processed data can be transmitted directly to a receiving station on the ground. The processed data can also be recorded in the data storage device in real time first, and then transmitted to the ground receiving station at an appropriate time. [0003] Each working mode of the digital transmission system consists of multiple instructions to form an instruction sequence, and different operating modes are realized by different instruction sequences. There are strict order and time int...
