Book Description
Mapping of the earth's magnetic field with satellites is of primary importance in the World Magnetic Survey. This importance stems not only from the operational capability to map vast regions in minimum time, but also from the capability to differentiate the causes of variations in the earth's field. Rocket and space probe measurements supplement satellite surveys in providing cross-ties for mapping and in finding the sources of field variations. For most of the survey objectives, highly accurate measurements are required. Thus, magnetometers based on nuclear or atomic resonance offer many advantages. Vanguard III, (1959 eta), with a proton precessional magnetometer, was an initial step toward field mapping with an absolute instrument. Optical pumping magnetometers now make possible continuous absolute measurements over the full range of earth field intensities with low power dissipation. The Orbiting Geophysical Observatory satellites will probably be the primary vehicles for future magnetic field surveys. These include satellites in highly eccentric orbits with small inclination, and satellites in polar orbits of low eccentricity. (Author).
