Great picture ... taken in 1992 with my daughter handling a GPS PATHFINDER.At that time no real time correction (except from rare L-Band provider) and only post-processing if needed.26 years after what has changed ? More GNSS constellations, cheaper equipments, algorithms and infrastructures ... Looks like it was yesterday for me.
