摘要
卫星导航和惯性导航采用深耦合方式实现导航作为世界上最先进的导航形式,在国防中的应用越来越广泛,但其在高动态下的性能需要验证。当前针对深耦合高动态下导航接收机的测试研究较少,本文介绍了基于卫星信号模拟器的测试系统组成及测试用高动态场景,运用模拟测试原理,通过对导航接收机在高动态下定位速度和跟踪灵敏度的测试及其结果分析,验证了导航接收机的深耦合功能,对此类接收机的测试方法进行了初步探究。
The satellite navigation and inertial navigation of using deeply coupled are the world＇s most advanced navigation form. With more and more wide application in defense, its performance in high dynamic state needs to be verified. There is a lack of study on test of deeply coupled receiver under high dynamic state at the moment. The composition of test systems based on satellite signal simulator and the test high dynamic authentication are described. The deeply coupled function of navigation receiver is veri-fied through testing location velocity and tracking sensitivity under high dynamic authentication and its analyzing their messurement results, a preliminary study on the navigation receiver test methods based on satellite signal simulator is presented.
