Processing method for upwards injecting multi-parameter instruction by agile satellite

Abstract

The invention discloses a processing method for upwards injecting a multi-parameter instruction by an agile satellite. According to the method, instructions generated when an on-satellite attitude control subsystem, a data transmission subsystem, a camera subsystem, a satellite affairs subsystem and other subsystems of the agile satellite execute mobile imaging tasks are formed into multiple instruction templates depending on typical working modes of various on-satellite subsystems and are stored in an on-satellite computer; the instruction templates corresponding to the types of the mobile imaging tasks are selected by a ground user, and a task number, an instruction template number and instruction parameters in the instruction templates are transmitted onto the satellite in accordance with a determined format of the satellite and the earth, and then an instruction set can be automatically generated by the on-satellite computer. Meanwhile, the on-satellite computer can modify contents in the instruction templates, add the instruction templates, and delete the instruction templates and the like at any time in accordance with an instruction on the ground. According to the method, not only can the complexity degree of instruction arrangement of the ground user be simplified, the upwards injecting data volume is greatly reduced, but also the reliability of instruction arrangement can be improved; particularly, the method provides a technique guarantee for task management and applications of the agile satellite.

Description

technical field [0001] The invention relates to an agile satellite multi-parameter instruction annotation processing method. Background technique [0002] The previous models of satellites did not have maneuvering actions when performing imaging tasks. The ground users turned on, took pictures, and shut down the camera subsystem on the satellite, and then downloaded the data to the ground receiving station through the digital transmission subsystem. The program-controlled instructions executed in chronological order are coded and formatted according to the satellite-to-earth communication format, and are uploaded to the satellite when the satellite is in transit. After receiving it, the on-board computer sends instructions to the sub-systems on the star in order to complete Mobile Imaging Mission. [0003] The high agility and high precision of agile satellites require the coordination of multiple subsystems such as the on-board star service subsystem, attitude control subs...

AI Technical Summary

Problems solved by technology

[0003] The high agility and high precision of agile satellites require the coordination of multiple subsystems such as the on-board star service subsystem, attitude control subsystem, camera subsystem, data transmission subsystem, and measurement and control subsystem. Huge, and the complexity of the relationship between instructions is greatly increased

If we continue to use the previous model of ground user programming instructions, it will not only make the command programming complicated, but also make the long-term operation and management difficult

Moreover, the satellite transit time is only about 10 minutes, so it is difficult to inject a large amount of command data into the

Obviously, the instruction arrangement method and above-mentioned format of previous models cannot achieve this purpose
