Rover Setup

Coordinate System

Choose a coordinate system based on the LKS92 datum (such as LKS92 / Latvia TM).

Vertical Datum

Choose the Latvia 2000 height vertical datum.

The LV_14 geoid is used to perform the transformation.


Consider the Latvia 2000 height vertical datum as LAS-2000,5 height in this case.

Base Setup

Your base or NTRIP service should be in LKS92.


The LKS92 datum is a national realization of ETRS89.

When setting up a base station on a benchmark, enter LKS92 geographic coordinates (lat/long) and ellipsoidal height in the ReachView 3 Settings / Base mode.
