Rover Setup

Coordinate System

Choose a coordinate system based on GGRS87 (such as GGRS87 / HEPOS) or HTRS07 (such as HTRS07 / TM07) datums.

Vertical Datum

Choose the Greece GREEKGEOID2010 height vertical datum.

The GreekGeoid2010 geoid is used to perform the transformation.

Base Setup

Your base or NTRIP service should be in HTRS07. The following methods are used to perform the datum conversion: GGRS87_HEPOS grid, Helmert (7-parameters).

note

The HTRS07 datum is a national realization of ETRS89.

The datum conversion from HTRS07 to GGRS87 / HEPOS uses the Helmert (7-parameters) transformation method and then the GGRS87_HEPOS grid.

When setting up a base station on a benchmark, enter HTRS07 geographic coordinates (lat/long) and ellipsoidal height in the Emlid Flow Base settings.
