  • Source: internal GPS of the mobile device or external GPS receiver connected via Bluetooth
  • Longitude, Latitude: current position
  • X, Y: current position in project's coordinate reference system
  • Horizontal and Vertical accuracy of the GPS position
  • Altitude: ellipsoidal height
  • Satellites (in use/view): number of satellites
  • Speed
  • Last fix: time of the last received GPS position
