Definitions

* 95% Circle of Error Probable (CEP) = 95% of the time the position readings will fall within a circle of the stated radius. 2cm accuracy requires an RTK option and RTK enabled Base Station.

** Not using DGPS and crossing the start/finish line at 100km/h.

*** Based on <50m brake stop distance.
