Hardware in the Loop Simulation System for Rapid Validation of High Accuracy Space Orbit Control Mission

Based on the traditional hardware in the loop (HIL) simulation system of spacecraft attitude and orbit control system (AOCS), a new simulation system is designed and realized for validation of time consuming and high accuracy space orbit control mission. In this system, an approach is proposed, which can accelerate process of simulation experimentation by super real time running of program in dynamics simulator. The implement planning, structure, components and working principle of the system are introduced. Then the two key problems are detailed, including exploring of the real time & super real time orbit and attitude dynamics model, and synchronization for states of hardware tested and test equipment. The system has been applied for development of AOCS successfully; its validity is illustrated by an instance.
