摘　　要：卫星系统的总体设计以及在轨运行等任务都离不开对其制导、导航与控制(GN&C)分系统的设计、优化与仿真演示,但GN&C分系统方案以及算法的复杂性对于GN&C分系统的快速设计、仿真与决策非常不利。采用Matlab/Simulink作为后台计算引擎、利用Matlab与VC混合编程,设计实现了一个卫星GN&C分系统建模与仿真软件环境。该软件环境能够屏蔽GN&C分系统的构建细节从而快速搭建具体的仿真应用,可实现对卫星GN&C分系统方案的快速仿真评估,并实现建模环境与具体的仿真应用相分离。The design,optimization and simulation of Guidance,Navigation and Control（GN＆C） system are necessary for both the design and on-orbit operations of satellites.However,the variety of GN＆C 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 GN＆C system,called GN＆C,is designed and implemented using Matlab/Simulink as a computation engine.The software can effectively filter out laborious details in building GN＆C simulation system,thus can evaluate the performance of the GN＆C system by simulation.
