Resolution No.1 (1985): Continuation of magnetic field satellites and associated ground measurements

IAGA, recognising the great improvement of our knowledge of the geomagnetic field because of the availability of MAGSAT data, noting that additional such satellites are essential for disciplines such as magnetospheric and ionospheric physics, magnetic exploration of the crust and studies of the Earth's core, endorses the recommendations of the International Working group on Magnetic Field Satellites, and urges again that a continuing program of satellite vector measurements of the geomagnetic field be initiated in the near future, and that the associated ground measurements which are needed for absolute reference and for modelling the main field be continued and, if possible, expanded.
