Abstract

The invention discloses a cross-platform extendible satellite dynamic simulation test system, which comprises a satellite attitude control system simulator, a flight environment and motion simulator, a satellite basic subsystem simulator and an operation monitoring and management system simulator. The satellite attitude control system simulator comprises a sensor simulator, a controller simulatorand an actuating mechanism simulator; the flight environment and motion simulator comprises an orbit and attitude dynamics resolver, a celestial body simulator, a kinematics and dynamics turntable, akinematics and dynamics translation platform, a hot vacuum and electromagnetic environment simulator and the like; and the satellite basic subsystem simulator comprises a power supply subsystem simulator and a remote measuring and remote control subsystem simulator. The operation monitoring and management system simulates functions of a satellite ground measurement and control center, such as remote measuring data decoding, remote control command generating, data archiving and analyzing and operation managing. The cross-platform extendible satellite dynamic simulation test system has strong extendibility, can be conveniently transplanted on a development and debugging platform, a distributed real-time simulation platform and an embedded semi-physical real-time simulation platform.

Description

technical field

[0001] The invention relates to a satellite dynamic simulation test system, in particular to a cross-platform scalable satellite dynamic simulation test system. Background technique

[0002] Aerospace engineering has the characteristics of hugeness, complexity and high comprehensiveness. Before the satellite goes into space, it needs to do full component testing and system simulation, so as to check the design scheme and existing problems of the system. With the deepening of space exploration, there are more and more types and styles of satellites, and there have been multi-satellite space missions, such as formation flight, rendezvous and docking, inter-satellite detection and tracking, and inter-satellite on-orbit module replacement and filling. The existing attitude control simulation test system for a single type of single satellite can no longer meet the demand.

[0003] The existing full-physical simulation and semi-physical simulation satellite attitu...
