The Use of GNSS in Sweden and the National CORS Network SWEPOS
Mikael Lilje, Peter Wiklund & Gunnar Hedling
Sweden was very early in introducing GPS as an effective tool for navigation, surveying and mapping. Lantmmteriet, the Swedish mapping, cadastral and land registry authority was one of the first countries in the world to have a national CORS as well as a nationwide network- RTK. We realized very early that applications as e.g. cadastral surveying and aerial photogrammetry would be much more efficient if GPS and a net of permanent GPS stations could be used. This lead to the establishment of the first stations in early 900s for applications that required metre accuracy in real time and centimetre with post-processing. The national CORS network SWEPOSTM, which last year celebrated 20 years, has been developed since then and is today a very efficient tool for real time surveying applications that require cmaccuracies as well as geodynamic research that requires long stable time series. The national RTK service celebrates 10 years in 2014. Today we have almost 3000 users of network-RTK in Sweden. The main users can be found at surveying companies and local authorities and the some of the fastest growing sectors of users are agriculture and machine guidance. The paper will describe the development of SWEPOS and how GPS, today GNSS, has become such an important tool for us. One of the main reasons for the success and the many users have been because the users as well as distributors have been involved in the development of SWEPOS since many years.
