| Abstract: | This paper developed a PDA positioning software using Visual Studio 2005 and Windows Mobile 5.0 SDK platform,after have discussed key technical issues of the VRS technology,serial communications,WinInet API HTTP communications and similarity transform.After coordinate transformation parameters are obtained,coordinate of rover can be displayed real-time.The system realized RTK positioning and result preservation in the local coordinate system.Analysis of test results shows that the system reaches a centimetre-level accuracy and has the practical application of a certain value. |
