United Kingdom

Rover Setup#

Coordinate System#

Choose a coordinate system based on the OSGB 1936 datum (such as OSGB 1936 / British National Grid).

Vertical Datum#

Choose one of the available vertical datums:

  • Belfast height
  • Douglas height
  • ODN (Offshore) height
  • ODN Orkney height
  • ODN height
  • St. Marys height
  • Stornoway height

The following geoids are used to perform the transformation:

  • OSGM15_Belfast
  • OSGM15_GB

The Belfast height vertical datum uses the OSGM15_Belfast geoid. All the other vertical datums use the OSGM15_GB geoid.

Base Setup#

Your base or NTRIP service should be in ETRS89. The OSTN15 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 ReachView 3 Settings / Base mode.
