swipos-NAV

swipos-NAV enables the reception of navigation corrections via GSM. The correction data are calculated from the data of the Automatic GNSS Network Switzerland (AGNES) and allow a GNSS positioning accuracy of up to half a meter with high-end devices in perfect conditions.

swipos-NAV is used for mobile mapping. On the left, there are two users in the forest with a GNSS receiver and a tablet. On the right a detail of the mapping application.
Using swipos-NAV for mobile mapping

swipos-NAV uses differential GNSS with code correction as technology.

Coverage

swipos-NAV is available throughout Switzerland wherever GNSS and GSM reception is possible.

For applications requiring pan-European coverage, the Galileo EGNOS cooperation agreement or, in the near future, the free Galileo High Accuracy Service (HAS) will be available.

Equipment

Ideally, a GNSS receiver with an integrated GSM module is required to use swipos-NAV. External GSM modules can only be used if the firmware of the GNSS receiver supports the control of such a module.

Comments

  • The accuracy specifications are based on the mean annual standard deviations of test measurements at swisstopo.
  • The measurement accuracy can vary in time, location and due to atmospheric influences.
