As collector has started to support high-accuracy receivers it would be good to have the ability to follow good survey practise for GPS measurements.
It would be good if we had to measure a point twice (say 20mins between each set of measurements) we could have the option of another set of measurements which would be used to calculate a weighted average position for the point using the two sets of measurements. This could also flag any error in a measurement if the 2 measurements did not agree within a certain limit.
The second measurement on the point is to obtain an independent fix by having different satellites in a different constellation.
