Embodiment

[0050] 1. Design and clarify the design input conditions required for satellite in-orbit application manipulation.

[0051] ①According to the user's needs, complete the design of the working mode of the satellite payload, including: the working mode of the payload (such as striping, scanning, beamforming, TOP_SAR, etc.), the working mode of the data transmission system (such as real transmission, recording, playback, recording while recording, Memory erasing, etc.), satellite platform working modes (such as emergency large-angle maneuver imaging, conventional small-angle side swing or upright flight imaging, etc.).

[0052] ②According to the typical working mode of the satellite in orbit and the characteristics of the time and frequency of use, the design of the principle of satellite on-orbit use is completed and clarified. Including the working mode, working time and switching rules between modes for a single imaging of the payload, the total imaging time and working times p...

Abstract

The invention discloses a loading task running control method aiming at the radar satellite on-orbit application. The method is characterized in that on the basis of a conventional remote sensing satellite loading task executing mode, the constraint condition of a ground running and controlling system is quantified, and the formats of an application task schedule and an application task data block are appointed, so that the running and controlling of the ground to a satellite is facilitated; meanwhile, the contents of detailed instruction groups, time constraint and compiling requirement in the instruction groups as well as task conflict interpretation and conflict handling requirements are transferred to a satellite on-orbit data management system from the ground running and controlling system; furthermore, a task legality autonomic interpretation control mechanism, a task block deleting and task revising mechanism and a earthward system telemetering feedback mechanism are added on the satellite, so that the loading task autonomic arrangement and control of the radar satellite on-orbit application is realized, and the conventional control convenience and emergency control ability of the satellite on-orbit running are improved; in addition, through providing an on-orbit software modification function, the reliability and safety of the satellite on-orbit application are greatly improved.

Description

technical field [0001] The invention relates to remote sensing satellite load task control technology, in particular to a load task operation control method for radar satellite on-orbit application. Background technique [0002] At present, the ground application control of remote sensing satellites in my country basically adopts the on-orbit operation control system of "static time constraints + command templates". Users realize daily task management through two steps: first, according to factors such as imaging requirements, satellite operation status, and ground resource availability, Carry out matching optimization of target, satellite and ground receiving resources, and formulate load work plan, ground tracking and receiving for each satellite's energy balance constraints, data balance constraints, attitude maneuverability constraints, thermal control temperature balance constraints, load timing constraints, etc. Then, according to the satellite observation plan, the perm...
