摘　　要：为进一步改善JTIDS/INS/GPS组合导航系统在现代联合作战中的作用,提出一种新的工作体制,即将差分GPS引入到JTIDS/INS/GPS组合导航系统中,可以显著提高导航定位精度。同时以Link 16的通信链路传输差分GPS的差分信息,节省系统资源,增强系统的可控性和抗干扰性。通过仿真对有无差分和差分基准站数量不同两种情况下的定位性能进行比较分析,验证了系统设计的有效性。A new system is which introduces the differential GPS to JTIDS/INS/GPS integration system. In the system, communication datalink of link16 transmits the differential information of the DGPS, so that it would take full advantages of the system resources and improve the system＇s controllability and antijamming performance. The performance of the JTIDS/INS/GPS integration navigation using the differential GPS information of one base station and different amount of base stations are assessed and compared to those without using the differential GPS information. Navigation accuracy based on the differential GPS is im proved according to the simulation of the new system.
