World Magnetic Model
The World Magnetic Model (WMM), produced jointly with the US National Oceanographic and Atmospheric Administration's National Geophysical Data Center, is the standard model in UK Ministry of Defence and US Department of Defense navigation and attitude reference systems and is also used widely in civilian navigation systems. The model is also used on marine and aviation charts and is revised every five years.

- The World Magnetic Model (WMM) is a standard model of the core and large-scale crustal magnetic field. It is used extensively for navigation and in attitude and heading referencing systems by the UK Ministry of Defence, the US Department of Defense, the North Atlantic Treaty Organization and the International Hydrographic Organization. It is also used widely in civilian navigation and heading systems. See http://geomag.bgs.ac.uk/research/modelling/WorldMagneticModel.html
