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,讨论了相对导航的观测模型,研究了几种导航源的特性。针对这几种主要误差源的特性,提出了降低误差源对导航性能影响的方法。
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 discussed. The characteristics of these error sources are researched and the methods of performance to navigation result are indicated.
