摘要
该文首先介绍了天线相位中心偏移和变化的改正原理,以及天线相位中心校正的发展过程;然后通过麻省理工大学研制的GAMIT基线解算软件里天线相位中心改正模型研究绝对相位中心偏移和变化对基线解算的影响;最后通过算例分析其影响并给出高精度GPS基线解算的建议。
This paper firstly introduces the basic principle of correcting the offset and variation of antenna phase center and the development of antenna phase center correction,then researches the influence of offset and variation of absolute phase center on the baseline resolution through the antenna phase center correction model in GAMIT baseline resolution software developed by Massachusetts Institute of Technology(MIT),and finally analyzes its influence by resolution examples and gives the proposals for the high-accuracy baseline resolution of GPS.
