高等级GPS网数据处理模型与方法分析

Model and Method for High Grade GPS Network Data Processing

目前,高等级测量控制网都是采用GPS静态测量技术,控制网要求严格设计与布设,严格按照规范进行观测。显然,观测耗时长、工作量极大,为如实的反映观测质量的优劣,减少补测返测,后期的数据处理显得尤为重要。如何研究和掌握一套高等级高精度GPS数据处理模型和方法,是测绘部门共同面临的重要课题,具有实用价值。本文主要阐述了高等级高精度GPS网数据处理模型和方法,并结合实例进行了数据处理和结果分析,得到了满意结果。

To build a high-grade GPS network needs many works, including design, observation, data processing and analysis. Study of model and method for that is full of significance in practical application. This paper mainly deals with the model and method of data processing for high-grade GPS network. Combining with the general GPS network, the authors of this paper process the GPS data using GAMIT software. And satisfied results have been achieved.
