Hardware in-the-loop simulation of celestial navigation systen

As a result of high spaceflight laboratory fees , it is impractical to take star-pictures real time in order to debug star sensor and test the algorithms of star map identification. In order to test the capability of identification algorithm, develop the star sensor quickly, as well as to reduce the cost and to improve the efficiency of developments, a new type of hybrid simulation system for celestial navigation is proposed in the paper. The configurations, functions and features of the system are introduced. The implementation methods and the specifications of the system are presented. It has the feature of flexibility and expansibility. By use of the proposed hybrid simulation system, some algorithms of star map identification and attitude determination can be effectively tested and validated in this platform, at the same time, using the system to make the hybrid real-time test, it is very significative for researching the dynamic capability of aircraft and system characteristic.
