摘要
构建一种星型结构的VRS网络RTK基线解算方式,提出适用于星型结构VRS网络RTK模糊度解算方法。针对这种星型结构分别对VRS网络RTK中电离层、对流层改正数的算法进行深入研究。最后通过两个试验对星型VRS网络与传统VRS三角形网络在网络模糊度解算与VRS网络改正数计算两方面进行了验证分析。试验结果表明所提出的星型结构VRS网络RTK在网络模糊度解算方面固定速度明显加快,在生成的网络改正数方面精度及可靠性更高。
A kind of baseline solution method of network RTK（VRS） based on star structure is established and a ambiguity resolution method is also proposed.Then further research is done to analyze the algorithm of ionospheric and tropospheric correction separately.Finally,the network ambiguity resolution and correction calculation in both star structure network and traditional triangular network are verified and analyzed through two tests.These tests indicate that the network RTK（VRS） based on star structure this paper proposed can obviously accelerate the fixed time of network ambiguity resolution,and can achieve higher precision and reliability in the generation of network correction.
