摘要
介绍了用于检测GPS接收机动态性能的天线转动测试系统,分析了天线圆周转动引起的多普勒频移变化规律,提出了利用多普勒频移反推卫星仰角的基本方法,同时给出了利用该转动测试系统在检验GPS接收机动态测量精度和跟踪性能等方面的实际应用。
The paper introduces the turning antenna testing system by which GPS receiver dynamic performance can be detected,and it analyses the doppler frequency change law resulted from GPS antenna turning. The paper puts forward the basic method in which satellite elevation can be calculated using doppler frequency. At the same time,it mentions the practical application in testing GPS measuring precision and tracking performance under dynamic conditions using the turning antenna testing system.
