VB3iS Position Accuracy

  • The standard positional accuracy of VBOX 3iS is 3 m (95 % CEP*) for Longitude and Latitude.
  • The height accuracy is 6 m (95 % CEP*).
     

* Circle of Error Probable (CEP): 95 % of the time the position readings will fall within a circle of the stated diameter. This error is due to the changing state of the ionosphere, constantly changing the time taken for the satellite signals to reach the earth, see GPS Errors and Noise.


The accuracy of the positional and height data can be improved using different types of Differential GNSS correction methods, more information on this is available here.
