With dead reckoning the error accumulates over time. Because GPS provides absolute positioning it does not have that problem.
- londons_explore 5y agoNot if your system is installed in a car which normally travels on roads... A simple Particle Filter conditioned on "90% chance the car is on a road or other drivable space" will robustly get rid of any error accumulation, leaving you a position estimate that may even typically be more accurate than GPS.
- dmlachap 5y agoI'm inclined to agree, but that requires your map to be consistently up-to-date, which may not always be practical.
