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 one of the available vertical datums:

  • Greece GREEKGEOID2010 height
  • HEPOS height

The following geoids are used to perform the transformation:

  • GreekGeoid2010
  • HEPOS

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).

remarque

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.
