Inaccurate Positions


#1

I’m finding some of the positions given by the eRide GPS to be more than 30 metres out, although the spec says less than 7 metres outdoors. Is this typical or is there something wrong with my unit?

Google for CEP (Circular Error Probability). Also check PDOP, HDOP, VDOP of your position fix.

I think it is normal if your application is static that not move ( the velocity = 0). It will be better if you try it in dynamic with a velocity !=0.
