Swiss Positioning Service swipos

The Swiss Positioning Service swipos provides the official spatial reference frame of Switzerland, based on the satellite systems GPS, GLONASS, Galileo and Beidou.

Function of the Swiss Positioning Service swipos
A man with a GNSS antenna stands in a meadow and receives data of the Swiss Positioning Service swipos via mobile phone network to improve his position

swipos is based on the automatic GNSS network Switzerland (AGNES), a network of continuously operating reference stations (CORS), covering all of Switzerland. swipos enables differential GNSS measurements of highest accuracy without the need to run private CORS.

The calculations use the four global navigation satellite systems (GNSS) GPS, GLONASS, Galileo and Beidou. To increase the GNSS-accuracy of 5-10 m, the correction service swipos uses a virtual reference station (VRS), which is interpolated for the current user position based on measurements from the surrounding ANGES stations. This method enables swipos-GIS/GEO to determine the position in real-time with a cm-range accuracy.

  • The positioning services are available 24/7
  • The services are monitored during the opening hours of swisstopo
  • There is no guarantee that the services are running without errors or interruptions

During the year 2021 swipos-GIS/GEO was unavailable for 6 minutes.
