Description
An advanced geomagnetic field model, more detailed than the WMM, with core field and secular variation coefficients for degrees 1–15 plus crustal field through degree 133 (18,210 non-zero coefficients). NGA recommends that all DoD systems use it. Sponsored by NGA and the UK DGC and developed jointly by NCEI and BGS.
