基于卫星模拟仿真平台的导航产品测试技术研究

摘要

为了实现对于卫星导航产品性能的有效测试,通过搭建卫星模拟仿真平台,对卫星导航产品测试技术展开研究,确定了灵敏度、定位时间和定位精度等测试项目,并针对测试项目,创新地提出了基于卫星模拟仿真平台的卫星导航产品性能测试方法.%With the increasing development of satellite navigation products, the demand for product testing is growing. The actual test on the road can not guarantee the controllability or repeatability of test signal, and can not meet the requirement of objectivity, fairness or consistency. In order to actualize effectual testing for the performance of satellite navigation products, the testing technology of satellite navigation products was investigated through setting up the simulation platform for satellite, and the testing items including sensitivity, positional time and positional accuracy were confirmed. Contraposing the above testing items, a method of testing satellite navigation products is innovatively proposed based on the simulation platform for satellite.
