Resolution No.14 (1967): Low altitude satellites with absolute magnetometers

The IAGA recognising that the study of the geomagnetic field requires comprehensive, and continuous, world-wide measurements and that the practicability of such observations by earth satellite has now been demonstrated, recommends that the appropriate agencies be requested to provide measurements by low altitude satellites recording data from absolute magnetometers. IAGA recommends at least two satellites at near polar inclinations, with their orbital plans at right angles, and a third spacecraft orbiting near the equator. IAGA further recommends that machine readable data from these orbiting magnetic observatories be made available to the World Data Center system in a timely way.
