Fluxgate Magnetometer

NSSDCA ID: 1972-005A-01

Mission Name: HEOS 2
Principal Investigator:Prof. Harry Elliot


A three-axis fluxgate magnetometer was used to measure magnetic field components of up to 16 nT with a digital resolution of 0.125 nT and from 16 nT to 150 nT with 1 nT resolution. Continuous field sampling occurred at a rate of one vector per 32 s. Faster rates were available in a limited duty cycle when core buffer storage was used. Rms noise measurements for one field component in a frequency band from 1 to 5 Hz were also made. The instrument was similar to that used for experiment 68-109A-02 carried on HEOS 1. The instrument worked normally until spacecraft reentry on August 5, 1974.
