Search Coil Magnetometer

NSSDCA ID: 1971-096A-05

Mission Name: S-Cubed A
Principal Investigator:Prof. Laurence J. Cahill, Jr.


This experiment consisted of two perpendicular search coil magnetometers, each mounted on a 61-cm radial boom. The plane of one magnetometer was perpendicular to the spacecraft spin axis, and the plane of the other was parallel to the spacecraft spin axis. This system measured magnetic fluctuations between 1 and 3000 Hz. The search coil outputs were routed to sets of filters, each of which was nominally sampled once each second. The experiment functioned normally until the latter part of March 1973 when a switch in the spacecraft analog multiplexer (which affects analog to digital conversion) began to fail. After that time, the only reliable data were analog broad-band data.
