An MGRS grid reference is a point reference system. When the term 'grid square' is used, it can refer to a square with a side length of 10 km (6 mi), 1 km, 100 m (328 ft), 10 m or 1 m, depending on the precision of the coordinates provided.
European Terrestrial Reference System 1989 (ETRS89) Military grid reference system, a variant of UTM designed to simplify transfer of coordinates. Modified transverse Mercator, a variation of UTM used in Canada with zones spaced 3° of longitude apart as opposed to UTM's 6°. Transverse Mercator projection, the map projection used by UTM.
German Naval Grid Reference (German:Gradnetzmeldeverfahren), was a system for referencing a location on a map. Introduced initially by the German Luftwaffe just before World War II , it was used widely in the German armed forces until 1943.
The Global Area Reference System (GARS) is a standardized geospatial reference system developed by the National Geospatial-Intelligence Agency (NGA) for use across the United States Department of Defense.

The World Geographic Reference System (GEOREF) is a geocode, a grid-based method of specifying locations on the surface of the Earth. GEOREF is essentially based on the geographic system of latitude and longitude , but using a simpler and more flexible notation .
Given that every projection gives deformations, each country's needs are different in order to reduce these distortions. These national projections, or national Coordinate Reference Systems are officially announced by the relevant national agencies. The list below is a collection of available official national projected Coordinate Reference ...
The grid reference schemes are defined in the article Universal Transverse Mercator coordinate system. The accuracy claimed for the UTM projections is 10 cm in grid coordinates and 0.001 arc seconds for geodetic coordinates.
