摘要
介绍了JTIDS相对导航的原理,研究了相对导航卡尔曼滤波算法和导航的源选择算法。分析了JTIDS相对导航的误差源,在TDMA消息分发机制中,编写了JTIDS相对导航模块并且进行了仿真,仿真结果体现了几种导航误差源的特性,为发展集成通信和导航系统提供了参考。
The principles of JTIDS relative navigation (RELNAV) are described. Kalman filtering and source selection algorithms for RELNAV are discussed. Major error sources are analyzed. Based on a TDMA message distribution mechanism, a JTIDS RELNAV module is designed to test the performance of navigation algorithms. Simulation results show the characteristics of these error sources and provide a reference for developing an integrated communication and navigation system.
