Relationship between GAMIT processing results of small GPS regional net and determination of IGS stations
Huang Yan · Journal of Nanjing University of Technology · 2010
A small global positioning system(GPS) net was composed of 5 stations in Jiangsu continuously operating reference stations(JSCORS) network,then GAMIT software was used to process their data from the 196th annual day to the 202th of 2008.The effect of international GPS service(IGS) station number(0-10) and their distribution on solution accuracy was discussed,and some conclusions were offered.The results showed that,for this small GPS regional net,it was better to choose IGS station to provide a reference frameworked when using GAMIT software dealed with observational data.But there is no necessary to choose the IGS stations located in the southern hemisphere.The selected IGS stations had to be distributed as even as possible,the 6-7 of them are satisfied.
