REACH M2: Coordinates and precision

[Florian (Florian Birot | Geomatics engineer)]

@phainein7

do the 190mm & 170mm values suggest the total offset distance with respect to the mounted GPS antenna

This is more a confidence interval than an actual offset.

@phainein7

So, on each side of antenna, 1/2 of these values.

The confidence interval is plus or minus this value, so 1/1 of these values on each side.
