Availability analysis of internet-based GPS RTK

WANG Hua,CHENG Pengfei,CAI Yanhui(Chinese Academy of Surveying & Mapping, Beijing 100039,China)  
RTK (realtimekinematic) is widely used in surveying and navigation applications for its high accuracy and being available in real time. Traditional RTK datalink is UHF (Ultra High Frequency) signal, which limits the coverage in real time positioning due to its sightline transmitting. With the popularization of Internet, the progress of easy mobile Internet access has triggered research activities around new methods of distributing GPSdata in high precision positioning systems. The architecture of internet transmission protocol TCP and UDP, the types and bytes of RTCM are discussed in this paper.The possibility of using Internet to transmit GPS positioning data are discussed together with its advantage and disadvantage.
