How do we do

Geo Smartphone Solutions

We apply sophisticated corrections models to correct raw GNSS measurements 
obtained from smartphone sensors. These corrections cover:

  • Satellite and receiver clocks
  • Precise satellite orbits
  • Troposphere corrections
  • Ionosphere corrections

Applying these model/ corrections:

  • Positioning accuracy before applying correction is 3 -5 meters (after ~20 minutes observation – static mode).
  • Using GNSS raw measurements and applying corrections to data, positioning accuracy can be improved to about 1,5 meter. (Phase 1 solution)
