摘要
该文从GPS基线解算的基本方法入手,着重讨论了不同观测量对GPS基线解算精度的影响,并结合三条不同长度的实测基线,计算比较了选择不同观测量情况下GPS基线解算的结果及精度,分析了原因,得到一些具有实际应用价值的结论。
This paper started with the basic method of GPS baseline processing, and mainly discussed the influence of different observations on GPS baseline processing precision. Combined with three measured baselines of different length, the baseline result and precision were computed and compared under different observations. This paper also analyzed the reasons and got some valuable conclusions in practical application.
