MIL-STD-2401, MILITARY STANDARD: DEPARTMENT OF DEFENSE WORLD GEODETIC SYSTEM (WGS) (11 JAN 1994)

MIL-STD-2401, MILITARY STANDARD: DEPARTMENT OF DEFENSE WORLD GEODETIC SYSTEM (WGS) (11 JAN 1994)., This standard specifies the requirements for use of World Geodetic System 1984 (WGS 84), the defining and derived parameters for WGS 84, and methods for transforming between WGS 84 and other geodetic systems. This standard applies to all DoD systems and products which require use of a World Geodetic System. A world geodetic system is a consistent global coordinate system which allows an unambiguous representation of positional information. Navigation solutions from the NAVSTAR Global Positioning System (GPS) and the Navy Navigation Satellite System (NNSS) are referred to this system. A WGS 84 ellipsoid provides a reference surface upon which coordinates are calculated and is particularly applicable to inertial systems. A WGS 84 Earth Gravitational Model (EGM) provides necessary force models for accurate global operation of strategic weapons, navigation, and satellite systems. Many MC&G products produced by other agencies and governments (and DMA products not yet placed on WGS 84) are not referred to the WGS 84. Parameters to transform these products to WGS 84 are part of this standard.
