Rover Setup

Coordinate System

Choose a coordinate system based on the ETRS89 datum (such as ETRS89 / Poland CS92).

The gugik-geoid2011-PL-EVRF2007-NH geoid is used to perform the transformation.

Base Setup

Your base or NTRIP service should be in ETRS89.

When setting up a base station on a benchmark, enter ETRS89 geographic coordinates (lat/long) and ellipsoidal height in the ReachView 3 Settings / Base mode.
