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.
