Important

Transformations are performed using open source grids from a BME (Budapest Technical University) project. These grids are not official VITEL grids and are not suitable for official land surveying work.

Rover Setup​

Coordinate System​

Choose a coordinate system based on the HD72 datum (such as HD72 / EOV).

Vertical Datum​

Choose the Hungary EHT2014 height vertical datum.

The EHT2014 geoid is used to perform the transformation.

Base Setup​

Your base or NTRIP service should be in ETRS89. The ETRS2EOV grid is used to perform the datum conversion.

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