Biaxial Fluxgate Magnetometer

NSSDCA ID: 1972-031D-02

Mission Name: Apollo 16 Subsatellite
Principal Investigator:Prof. Paul J. Coleman, Jr.


The Apollo 16 lunar-orbiting subsatellite magnetometer was a boom-deployed biaxial fluxgate instrument. One of its axes lay along the satellite spin axis. The other lay in the spin plane. A sun-pulse generator provided the phase information needed to obtain the direction of the magnetic vector. The spin period was 5.175 s. The dynamic ranges of each sensor were plus or minus 50 nT and plus or minus 100 nT. Otherwise it was identical to the Apollo 15 subsatellite magnetometer (71-063D-02). The instrument's useful life was terminated on May 29, 1972, when the satellite impacted the moon.
