摘要
介绍了捷联惯导与天文导航(SINS/CNS)组合导航仿真方案,简要设计和实现了SINS/CNS组合导航软件仿真平台;以Kalman滤波为基础,通过将SINS和CNS所测得的飞行器相关姿态和位置信息进行数据融合,估计出组合导航系统的误差状态量,进而修正SINS的位置、速度和姿态,最后在该系统下进行仿真,验证了这种设计方案的可行性和有效性。
The research on simulation software of SINS/CNS is very important to the conceptual definition,system design and development.In this paper,a scheme of integrated SINS/CNS is proposed and a simulation software of the integrated SINS/CNS Navigation system is designed and implemented.SINS and CNS can provide corresponding attitude data.Fusing these data can estimate the error state value of integrated navigation system and correct the position of aircraft,velocity and attitude angle based on Kalman filter.The applicability of the design method is tested and analyzed.Result shows that the simulation software is feasible and useful for further studies.
