摘要
本文对 GPS卫星播发的预报星历进行了分析 ,主要讲述 GPS接收机接收到的二进制预报星历文件的详细格式 ,将其解码并生成 RENIX2 .0标准格式文件 ,利用解码获得的卫星轨道参数来计算GPS卫星坐标 。
This paper analyzes the forecasting ephemeris transmitted by GPS\|satellites and describes and detailed format of the binary ephemeris document received by GPS\|receivers.The document is then decoded into the standard format in RENIX2\^0 and the orbit parameters of satellites are obtained.The calculation of GPS\|satellites coordinates and satellites forecasting are performed with these parameters.
