Abstract

The invention provides a verification system of an autonomous orbit control algorithm. Through a simulation computer, a spaceborne computer, a navigational star simulator and a GPS receiver, an autonomous orbit control closed loop test system is established on the ground. The spaceborne computer carries out calculation according to current position information sent by the GPS receiver, and controls and determines whether the autonomous orbit control algorithm is effective according to a result of comparing current attitude data fed back by the simulation computer, current orbit data, preset attitude data and orbit data. The test system can be established on the ground, and effectiveness and accuracy of autonomous orbit control algorithm operation are verified.

Description

technical field [0001] The invention relates to the field of satellite control, in particular to a verification system for an autonomous orbit control algorithm. Background technique [0002] During the satellite's in-orbit operation, the satellite-ground circuit is generally used to control the satellite attitude and orbit, generate or issue control commands according to a given control law, and generate control forces and moments for the satellite through the on-board actuators. Due to the constraints of satellite missions, the traditional satellite-earth loop control method cannot be used for orbit control. It does not rely on ground intervention and is completely autonomously controlled by spaceborne instruments. Therefore, an autonomous track control system needs to be built and verified on the ground. [0003] There is an autonomous orbit control algorithm running in the autonomous orbit control system. The autonomous orbit control algorithm plays a key role in the co...
