They probably use some RTK / dGPS setup for increased accuracy, which does need calibration.

- PragmaticPulp 6y agoActual RTK/dGPS makes GPS more accurate, not less. If it doesn’t lock, the software should fall back to regular GPS. Unless they were abusing the system by putting the dGPS reference station on a moving vehicle going the opposite direction or simply feeding spoofed correction data into the GPS.
- neeleshs 6y agoI'm ignorant about speed tests. Given that distance is constant, wouldn't two synchronized timers be simpler than using GPS? And potentially more accurate?
