Reply to comment by Industrial_Jedi in Researchers have developed an alternative positioning system that is more robust and accurate than GPS, especially in urban settings. The working prototype that demonstrated this new mobile network infrastructure achieved an accuracy of 10 centimeters. by the_phet

We can do survey-grade observations while in motion using RTK, the only caveat is you have to maintain satellite lock otherwise you have to re-initialize. The systems are sophisticated enough now that it isn’t much work to setup. Some of my favorite projects I’ve done involved mounting a RTK GPS to an ATV/quad and driving back and forth across a 400-acre farm for a topo survey, with the GPS automatically taking shots every 20 feet. I’d say the more efficient way to do it nowadays would be with drone photogrammetry.
