应用单组广播星历适时确定GPS卫星的位置

Use of a Group of Broadcast Ephemeris to Determine Timely the Position of the GPS Satellite

对只接收到一组GPS卫星广播星历的情况下应用广播星历确定卫星位置的方法进行了研究,通过与精密星历进行比较,对卫星位置的定位精度进行了说明。

In the paper, a research is made on the method of using the broadcast ephemeris to determine the position of the satellite in the case that only one group of broadcast ephemeris of the GPS satellite are received, and then the positioning accuracy of the satellite position is described based on comparison to the precise ephemeris.
