Surveying GPS can do that with WAAS and a bunch of integration time and extra receivers, but not in real time: https://www.gps.gov/systems/gps/performance/accuracy https://www.gps.gov/systems/gps/performance/accuracy So that's why I think they need to have a high resolution, close range, 3d positioning method for the final seconds.
