Mission Name: HEOS 1This experiment was designed to measure magnetic field components up to 64 nT with an accuracy of 0.25 nT using a boom-mounted triaxial fluxgate magnetometer. The HEOS 1 spacecraft was launched into a highly eccentric orbit so that the magnetometer measured magnetic fields within the magnetosphere and the transition and interplanetary regions. The magnetometer operated continuously in two modes. One gave a continuous series of vectors sampled at 48-s intervals. The other operated via a 16-kb data store with a variety of measurement programs and options including command or automatic replay, shock type event detection, etc. The experiment operation was normal until spacecraft reentry (October 28, 1975). However, data acquisition became intermittent late in the spacecraft life, and data accuracy decreased somewhat. For further details, see Hedgecock, Sp. Sci. Instrum., v. 1, p. 53, 1975.
