I wonder what exactly the meaning is of the GPS Accuracy value which is in the register with address 183:
Does it refer to the max radius of the circle around a true point where a receiver might plot a value? I other words: if GPS accuracy would have the value of 4, would that mean that in 98% of the time a receiver would plot a point of max 4 meters from the true point?
Or it is this accuracy value more of a specification for error propagation, such as DOP or GDOP (link points to wikipedia page)?
Thanks a lot!
