四种精密卫星钟差插值方法的比较

Comparision of Four Interpolation of Satellite Clock Bias

利用四种插值方法加密IGS网站下载的15 min和30 s卫星钟钟差改正,分别与IGS网站下载的30 s钟差数据以及CODE网站下载的5s钟差数据比较,试验表明,两种加密情况下宜选用线性分段插值。

We use four methods of interpolation of satellite clock bias downloaded from IGS.The results of interpolation are compared with data from both IGS and CODE.The results show that,piecewise linear interpolation have a better performance in those two situation.
