The Study of Geometric Distribution of Datum Points to the Accuracy of the Impact in GPS Control Network
XU Chang-rong · Anhui nongye kexue · 2011
Starting with a horizontal control network,TGO(Trimble Geomatics Office) software is used for static data processing of three groups of representative point-position combinations.By analysis and comparison,optimum geometric position distributions of datum points is obtained so as to improve the GPS positioning accuracy.
