Space environment (natural and artificial). Geomagnetic reference models Ingestion-build-82061 Provides guidance for practical implementation1 Scope This International Standard defines reference models representing the geomagnetic field. It closely mirrors and clarifies specifications which have been in use for many decades. The approach is to represent the corresponding scalar magnetic potential by a spherical harmonic expansion having specified numerical coefficients, called Gauss coefficients. This International Standard covers models in which, at any one time, changes of the magnetic
