Design of a HLA-Based Simulation for Satellite Autonomous Navigation

In this paper, a simulation based on HLA is designed for the research of satellite autonomous navigation technology. According to the basic theory of this field, the simulated scene of simulation is schemed. After the analysis of required functions, a framework of HLA - based simulation for satellite autonomous navigation is presented. Then the action of satellite, star, and controller which are primary federates in the simulation is modeled. Followed that, corresponding classes of these federates are designed. At last, the time advancing rule and management policy in this simulation are designed and illuminated. Through the test platform provided by the simulation based on the resolution described above, the demonstration and critical technology verification of satellite autonomous navigation can be implemented.
