| Abstract: | It is proved by GPS surveying practice that GPS network structure have remarkable influence on GPS positioning precision.In order to understand fully the relationship between the GPS positioning precision and its network structure,a high precise special-purpose testing network has been built at the northwest part of Shandong province in China.The special-purpose testing network is built by the precision ETS(electronic total station) and the precision leveling.This paper introduces the basic circumstances of the contrast test of GPS positioning precision through different network combination in the special-purpose testing network.It gets initial results of relationship between the GPS positioning precision and its network structure. |
