Implementation of modeling and simulation software for satellite Guidance, Navigation and Control

The design,optimization and simulation of Guidance,Navigation and Contro(lGNC) system are necessary for both the design and on-orbit operations of satellites.However,the variety of GNC system schemes and algorithm complexity are detrimental to the rapid design,simulation and decision-making.To address the issue,a modeling and simulation software environment pro- grammed by VC and Matlab for satellite GNC system,called GNC,is designed and implemented using Matlab/Simulink as a computation engine.The software can effectively filter out laborious details in building GNC simulation system,thus can evaluate the performance of the GNC system by simulation.
