提出一种组合导航方案,该方案在硬件上采用全捷联的结构,在算法上将捷联星光跟踪仪(strapdown startracker,SST)的姿态信息,高动态GNSS的位置、速度信息与捷联惯导进行组合滤波,全面提高导航精度。设计并实现了弹道导弹GNSS/SST/SINS组合导航系统实时仿真平台,仿真结果表明了该组合方案的稳定、可靠性。
This paper presents a new integrated project, which uses strapdown sensors and fuses the information of the attitude of strapdown star tracker(SST), the position and velocity of the high speed GNSS and the corresponding information of SINS to filter. Meanwhile the design of the simulated real time GNSS/ST/SINS platform has been realized. The result shows that the system is robust and reliable.
