| 摘 要： | TEQC是由UNAVCO Facility研制的GPS数据预处理软件,可进行单历元C/A码伪距单点定位的计算,获得各历元GPS接收机的WGS84坐标。利用TEQC对大量GPS观测数据的计算表明:TEQC软件的单点定位结果在东坐标和高程方向上带有明显的系统性偏差。作者研制的单点定位软件GPP,由于考虑了地球自转、对流层折射和电离层折射等误差对GPS定位的影响,因此单点定位的结果较为准确,而且对上述系统性偏差产生的原因进行了分析和探讨。

| Abstract: | TEQC is a software for GPS data processing which is developed by UNAVCO facility. It can be used to perform point positioning based on the C/A code and get the WGS84 coordinate of the receiver epoch by epoch. However, the results for Point Positioning have systematic errors on elevation and direction of east coordinate. On the assistance of self-developed GPP software, the authors analyze these systematic errors in details, and give some conclusions in the end. |
