Abstract
In this paper short baseline vector data of plain area, hilly area and island area from GNSS-C network in the coastal areas of south China are selected .Two different estimation strategy with and without tropospheric delay estimation are used to estimate the accuracy of data process in different geographic environment, The experimental results show that both the accuracy U component with tropospheric delay estimation and without tropospheric delay estimation are good in the three regions, but the accuracy of the latter is better than the former.In terms of baseline repeatability of the whole network, the accuracy of solution with tropospheric delay estimation and without the estimation of tropospheric delay is good, but the accuracy of the former is slightly better than the latter.
