Abstract

The invention discloses a semi-physical simulation system for attitude control of a star-arrow integrated spacecraft, which relates to the semi-physical simulation system for control of the star-arrow integrated spacecraft. The invention solves the problem that the conventional semi-physical simulation system for the attitude control of the spacecraft cannot simulate the spacecraft from a launching point to an active operation stage attitude control system. A simulation signal input or output end of a real-time simulator is connected with a simulation signal output or input end of an onboard computer; a wireless signal input or output end of a stage wireless communication module is connected with a wireless signal output or input end of the real-time stimulator; and a signal output or input end of a ground wireless communication module is connected with a signal input or output end of a ground control module. The system is suitable for the stimulation of the attitude control of the star-arrow integrated spacecraft.

Description

technical field [0001] The invention relates to a satellite-rocket integrated spacecraft control semi-physical simulation system. Background technique [0002] At present, due to the long development cycle of spacecraft, high cost, high launch requirements, and slow response, China is still unable to quickly build a space-based information system, and lacks the ability to observe sudden natural disasters in a timely manner and respond quickly. In order to effectively utilize system resources and reduce assembly and testing time, Harbin Institute of Technology proposed the concept of a satellite-rocket integrated spacecraft that organically combines satellites and carriers. [0003] The semi-physical simulation of spacecraft control system is a unique simulation method in the process of developing spacecraft. It uses the air-bearing turntable as a motion simulator and combines some real objects to build a semi-physical simulation environment for simulation verification of con...
