Local calibration of GNSS

Open ollesmaps opened this issue 1 year ago • 2 comments

Probably a naive idea: Would that be possible to enhance the GNSS signal by very local mapper position info? At many locations during the mapping day in the field (with Android device) I know exactly where I am - based on laser, aerial data. And GNSS is a little or more off this location.

Would that be possible to add this very local "differential correction" to the triangulation? Maybe just add a vector (my position minus GNSS)

  • for the next 5-10 minutes and then come back to the GNSS
  • or add a second differential localisation target (for the time a new button is pushed)

My observation is: if there is a mistake in the GNSS, it is usually "parallel", at least for some time. The added vector would eliminate it.
