OSGB36 is based on the Airy ellipsoid, a reference ellipsoid named after George Biddell Airy. Introduced in 1830, it is a best fit for the Britain region. More modern mapping tends to use the GRS80 or WGS84 ellipsoid, as used by the Global Positioning System. The Airy ellipsoid assumes the Earth to be about 1 km smaller in diameter than the ...

The Coordinate Transformation Tool transforms GNSS based ETRS89 latitude and longitude or cartesian XYZ coordinates to the equivalent OSGB36 National Grid eastings and northings, and vice-versa, using Ordnance Survey's National Grid Transformation OSTN15.

OSGB36. The OSGB36 ellipsoid is a revision of work begun by George Airy the Astronomer Royal in 1830, when the OS first undertook to make a series of maps that covered the entire country. It provides a good fit for most of the British Isles. EDM50. The European standard ellipsoid is a compromise to get a good fit for most of Western Europe.

May be taken as approximate transformation OSGB36 to WGS 84 - see code 7710. Replaces OSGB36 to ETRS89 (1) (tfm code 5338). Information source: Ordnance Survey of Great Britain.

Using OSTN15 and OSGM15, OSGB36 and ODN coordinates are obtained by 3‑D transformation software that converts ETRS89 GNSS coordinates obtained from OS Net into the equivalent OSGB36/height datum position.
