目标模拟器用来模拟作为卫星姿态敏感器的参考目标(太阳、地球和恒星等)的环境特性。
Target simulators are used to simulate the environment character of reference objects (the sun, the earth and stars) as satellite attitude sensors.
介绍了卫星惯性姿态敏感器(IAS)的工作原理，分析了惯性姿态敏感器设计及关键技术。
The principle of inertial attitude sensor (IAS) in satellite is introduced in this paper, and also are the design and key technology of IAS.
同时深空环境对姿态敏感器选用造成了限制，使得从控制回路外部引入参考姿态指令成为必然。
Moreover, the reference attitude command must be imported from out of the control loop, considering the constraint to attitude sensors selection due to deep-space environment.
