| 摘 要： | GPS长基线数据处理在大地测量和大型精密工程中有广泛的应用,GAMIT等国际高精度GPS数据处理软件虽能满足GPS长基线数据处理的解算精度要求,但操作复杂,且对用户的GPS理论有较高的要求。本文在分析长基线GPS数据处理中各类因素影响及误差消除方法基础上,结合图形用户界面程序设计思想,设计并实现了GPS长基线数据处理软件。经不同长度的基线数据解算结果表明,该软件可实现上千公里基线的解算,基线解算精度高,与GAMIT的解算精度相当,且解算过程自动化程度高,用户操作简单,为大范围高精度GPS数据处理提供了一种简便可行的平台。

| Abstract: | GPS long baseline data processing is widely used in geodesy and large-scale precise engineering surveying.International high-precision GPS data processing software,such as GAMIT,can satisfy the precision requirement of the long baseline data processing,but the processing procedure is complicated and the user must be familiar with the knowledge of GPS theory.In the paper,GPS long baseline data processing software was designed and realized,based on studying the influences of the important factors in long baseline data processing,and methods of eliminating the errors in GPS measurements,with the graphic user interface programming.Experiments with different baseline lengths were carried out,and the results indicated that the proposed software could resolve GPS data with the baseline length up to thousands of kilometerd,and the precision of the resolved baseline reached the same level of GAMIT solution.The proposed software provided a convenient and feasible approach to realize the long rang and high-precision GPS data processing,with a high automation level and easy usage. |
