摘要
本文主要介绍了GAMIT数据处理软件的主要模块和基线解算流程,并阐述了GLOBK软件的主要应用及利用其进行网平差的方法。最后结合新疆似大地水准面精化项目GPS网观测数据进行分析,给出了GAMIT软件的基线解算结果以及质量评价,同时采用GLOBK软件进行了网平差,并对平差后的点位精度进行了分析评定。结果表明,数据处理的精度达到了项目技术设计的要求,获得的高精度控制点坐标为今后基础测绘基准的最终建立提供了科学的依据,也为建立高精度、高分辨率的似大地水准面提供了可靠和精确的数据。
This paper mainly introduces the main modules of GAMIT data processing software and the baseli-ne solution process,and describes the main application of GLOBK software and the method of network adju-stment.Finally,combined the analysis of Xinjiang quasi geoid project GPS network data,gives the GAMIT software baseline results and quality evaluation,at the same time the network adjustment by using GLOBK s-oftware,and the adjustment after the point precision is analyzed and assessed.The results show that the prec-ision of data processing to project technical design requirements,to obtain high precision coordinates of the c-ontrol points for the foundation of the surveying datum set up to provide a scientific basis,but also provide reliable and accurate data for the establishment of high precision and high resolution quasigeoid.
