JTIDS惯导GPS组合导航算法研究

针对JTIDS相对导航算法在实际应用中存在的不足,比如位置信息更新率较低、无姿态信息等,结合惯导系统、GPS卫导系统的导航优势,研究了JTIDS相对导航与惯导/GPS进行组合的导航算法,对两种导航算法即JTIDS/惯导组合导航算法、JITDS/惯导/GPS组合导航算法进行了仿真对比分析,验证了导航算法的有效性,仿真结果表明组合了GPS的导航算法比没有组合GPS的算法,较大程度提高了定位精度,仿真分析结果为实际工程提供了一定的理论参考。

Integrated Navigation Algorithm based on JTIDS/INS/GPS

Aiming at the deficiencies of JTIDS relative navigation algorithm in the practical application, such as fairly low position updating frequency, lack of attitude information and so on. By integrating the advantages of INS and GPS, the integrated navigation algorithms based on JTIDS/INS and based on JTIDS/INS/GPS are studied and compaired. Simulation and analysis results indicate the effectivity of integrated navigation algorithm, and that the integrated navigation algorithm based on JTIDS/INS/GPS could achieve better position precision than based on JTIDS/INS. And these results could provide certain theoretical reference for practical project.
