JTIDS/BA/INS/GPS组合导航处理器软件设计与仿真

Design and Simulation of JTIDS/BA/INS/GPS Navigation Processor Software

针对JTIDS导航定位功能在现代军事作战中存在的不足,综合考虑导航定位精度和可靠性,设计了JTIDS/BA/INS/GPS组合导航处理器软件,重点研究了JTIDS/BA/INS/GPS组合导航卡尔曼滤波算法。采用滤波器分解和观测量序贯处理技术,提高滤波定位的实时性;对于不同导航参数的校正,分别采用开环校正、闭环校正和误差估值累加校正的方式,可在保证精度的条件下简化工程实现。为评估组合导航方案,开发了JTIDS多成员组网工作仿真软件,通过仿真验证了组合导航处理器软件在组网工作中的稳定性,以及JTIDS/BA/INS/GPS组合导航滤波算法的有效性。

JTIDS/BA/INS/GPS integrated navigation processor software was designed to improve JTIDS navigation performance, and the navigation Kalman filtering algorithm was proposed in detail with consideration of navigation precision and reliability. Filter decomposition and observations recurrent process were used to improve real time of navigation. Open-loop, close-loop and accumulated errors rectification were used separately for different navigation parameters. JTIDS multi-member networking sim- ulation software was developed to evaluate navigation algorithm. Simulation results validate the stability of the navigation processor software and the effectivity of the integrated navigation algorithm.
