scope:
This specification is designed to provide guidelines for the preparation and use of the World Magnetic Model (WMM) and the charts and grid tables derived from the model. This specification also provides guidelines for the preparation and use of computer programs and subroutines that compute the model magnetic field elements, namely the declination (D), inclination (I), total intensity (F), horizontal intensity (H), northerly component (X), easterly component (Y), downward component (Z), and grid variation (GV) at given locations and times.
Purpose. The purpose of this document is to specify the WMM and the products that are derived from the model.
intended Use:
The World Magnetic Model is intended for use in the public, private and governmental domains for such purposes as aid to navigation, attitude determination, aid to target acquisition, other... View More
