The GPS datasheet accuracy is CEP at 24 hours stationary, a common test condition for GPS. CEP is a 50% confidence number. Like other single (non-differential) GPS units, our accuracy is limited by constellation geometry, atmospheric, and clock error effects (largest contributors when selective availability is not included.) This pegs best performance at approximately 5 meters RMS dynamic. This is improved for areas where WAAS is enabled.
