| Abstract: | This paper firstly introduces Ntrip protocol and User's authorization which is uploaded to VRS control center with rough position by GPRS.It could send the RTCM difference correct information to GPS rover by Serial Module to accomplish the difference and to improve the collect accuracy by GPS data.And then it describes how to realize the mobile GIS system based on ArcGIS Mobile.Finally,it summarizes the development of key technical problems that is encountered. |
