基于多组星历参数的后处理伪距差分算法

Post treatment pseudorange differential GPS arithmetic based on multi-ephemerises

在后处理伪距差分中用所需时刻前后的星历参数相结合的方法计算卫星位置,计算动态站的精确位置,可能比只利用所需时刻前的星历参数计算得到更高的定位精度。从所求时刻前后的星历参数相结合求卫星位置,进行动态站的伪距差分定位,实验结果表明定位精度进一步提高。

It is possible to receive all-day ephemerises when positioning a object using post treatment pseudorange differential GPS. So the satellite situation may be calculated by the followed ephemerises. Using both ephemerises before the time and after the time, getting precise locomotive station situation are possible.
