Definition

Magnetic field. A vector force field produced by moving electrical charges (electric currents and magnetized material).

Satellite. A compact body orbiting another body in space, and, in this case, human-made container carrying equipment for measuring magnetic fields (magnetometers) and the direction of its sensors.

Introduction

Magnetometers (qv) onboard Earth-orbiting satellites measure precise near-Earth magnetic fields in space from sensors mounted on booms to reduce interference from the spacecraft’s magnetic fields. Since the dawn of the age of the Earth-orbiting satellites, the POGO series (three missions during 1965–1971, periapsis (lowest altitude) of about 400 km, scalar only, Cain (2007)), Magsat (6 months during 1979–1980, alt. 325–550 km, Langel et al. (1982)), CHAMP (2000–2010, alt. 300–450 km, Lühr et al. (2009)), Ørsted (1999–2010+, alt. 650–850, Olsen (2007)) and Ørsted-2/SAC-C (2000–2004, alt. ∼700 km, Olsen (2007)) satellites have made significant...
