GPS基线处理要点

1、GPS测量数据处理一、实验目的      1、掌握GPS接收机采集的数据下载工具和使用；      2、掌握TGO软件进行基线解算和闭合环路的检验。二、实验软件       GPS后处理软件：HDS2003软件 三、实验内容：用中海达软件完成GPS静态处理，包括基线结算，网平差等过程， 五、 实验步骤1. 数据导入， 2.基线解算：（1）基线解算设置 数据采样间隔、截止高度角、大气改正模型、模糊度解算方法、

2、参考卫星、采用的数据（历元）、观测值（单频、双频）（2） 基线解算 将为通过基线重新基线结算设置 ，并进行结算直到全部基线通过结算。 点击搜索基线闭合差使同步环和异步环都合适。由于部分数据质量的原因可能导致基线解算失败，可通过查看基线解算后卫星观测值的残差来判断质量较差的数据，可以通过更改基线解算的设置来处理，如果更改设置后个别基线仍不成功，则应该删除掉 基线报告 基线简表JS04JS05.3311L1 & L2X 增量Y 增量Z 增量距离三差解0.0049180.76271.525058.9447190.1367双差解0.0044180.75511.515758.9397190.12
