SWEPOS ®- THE SWEDISH NETWORK OF PERMANENT GPS REFERENCE STATION (Status February 2001)

By Gunnar Hedling, Bo Jonsson, Christina Lilje and Mikael Lilje

Abstract

Since 1 st of July 1998 the Swedish network of permanent GPS reference stations, SWEPOS, is operational in IOC mode, i.e. positioning in real time with meter level accuracy and by post-processing with centimetre level accuracy. Future plans are for monitoring in real-time on the centimetre/decimetre level. Twenty-one of the SWEPOSstations are mounted on bedrock and have redundant equipment for GNSS-observations, communications, power supply etc. Another ten stations are mostly located on the top of buildings and have less redundant equipment. The main task for these stations is realtime RTK services. All the SWEPOS stations have real time connections to the control centre in Gävle through leased lines (using the TCP/IP protocol). The purpose of SWEPOS is to: – provide L1 and L2 data in RINEX format for post-processing – Provide DGPS and RTK data in RTCM format to real time distributors – act as high precision control points for Swedish GPS users and act as the basis of the Swedish national reference fram
