Fluxgate Magnetometers

NSSDCA ID: 1971-096A-04

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

Description

This experiment was designed to measure the vector magnetic field and fluctuations over the spacecraft's orbit. This set of magnetometers consisted of a triaxial fluxgate system. These, along with a commandable flipper mechanism to check zero levels, were housed in the sphere at the end of the single boom extending 76 cm along the spin axis. This system measured the vector magnetic field from dc to 10 Hz with a sensitivity of less than 5 nT. The magnetic field was sampled 30 times each second. The experiment functioned normally until the latter part of March 1973 when a switch in the spacecraft analog multiplexer began to fail. No useful data were obtained after that time.
