Question

Hey, 

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!

Hello,

Thank you for contacting.

Accuracy means the radius of the circle around true point , meaning the true point is within the radius  of the Accuracy value.

Thanks.
