Applications of GNSS-Pro software for processing GNSS short baseline networks in Vietnam

Abstract

In the framework of a Natural Resources and Environment Ministry level project, chaired by the Vietnam Institute of Geodesy and Cartography, we have established GNSS-Pro software for processing GNSS short baseline networks. The software can process carrier phase measurements from single or dual frequency receivers for the two satellite systems GPS and GLONASS simultaneously. This paper presents the results of treatment an illustrated cadastral GNSS network in Hai Duong province by GNSS-Pro and compared with other commonly used software packages such as Leica Geo Office (LGO) and Trimble Business Center (TBC). Result comparisons showed that although GNSS data collected in the unfavorable conditions, GNSS-Pro still offers fixed solution for all baselines with centimeter level accuracy
