Resolution No.2 (2001): Satellites and magnetic observatories

IAGA, welcoming the recent success of satellites for mapping the Earth's magnetic field, recognising that geomagnetic observatories provide essential ground-based support for satellite surveys, that satellite and observatories fulfil complementary roles, and that important scientific and technical application requirements can only be met by magnetic observatories, emphasises that the importance of maintaining a global network of geomagnetic observatories is increased rather than diminished by the availability of satellite magnetic survey data.
