Rover Setup

Coordinate System

Choose a coordinate system based on ETRS89 (such as ETRS89 / Austria Lambert), MGI (such as MGI / Austria East Zone), or MGI (such as MGI / Austria East Zone (2021)) datums.

Vertical Datum

Choose one of the available vertical datums:

  • EVRF2000 Austria height
  • GHA height

The following geoids are used to perform the transformation:

  • GEOID_GRS80_Oesterreich
  • GV_Hoehengrid_plus_Geoid_V

Base Setup

Your base or NTRIP service should be in ETRS89. The following methods are used to perform the datum conversion: AT_GIS_GRID grid, AT_GIS_GRID_2021 grid.

note

You can't use this datum conversion from ETRS89 to MGI for cadastral purposes. It does not comply with the rules for control network tie-in as per Paragraph 3 of the Land Survey Regulations (Vermessungsverordnung) 2010.

When setting up a base station on a benchmark, enter ETRS89 geographic coordinates (lat/long) and ellipsoidal height in the Emlid Flow Base settings.
