Rover Setup​

Coordinate System​

Choose a coordinate system based on ETRS89 (such as ETRS89 / UTM zone 29N), IRENET95 (such as IRENET95 / Irish Transverse Mercator), or TM75 (such as TM75 / Irish Grid) datums.

Vertical Datum​

Choose one of the available vertical datums:

  • Belfast height
  • Malin Head height

The following geoids are used to perform the transformation:

  • OSGM15_Belfast
  • OSGM15_Malin

Base Setup​

Your base or NTRIP service should be in ETRS89 or IRENET95, depending on which datum is used. The TM75_ETRS89 grid is used to perform the datum conversion.

note

The IRENET95 datum is a national realization of ETRS89.

When setting up a base station on a benchmark, enter ETRS89 or IRENET95 geographic coordinates (lat/long) and ellipsoidal height in the Emlid Flow Base settings.
