Vector Magnetometer

NSSDCA ID: 1979-094A-02

Mission Name: Magsat
Principal Investigator:Dr. Robert A. Langel, III


The vector magnetometer consisted of three fluxgate sensing elements aligned along orthogonal axes. The output of each vector sensor was converted to a digital word by an analog-to-digital converter. The outputs of all these axes were sampled essentially at the same time. Sixteen vectors were measured per second. Each vector measurement had a resolution of better than 1 nT and an absolute accuracy of better than 6 nT rms when referenced to a geocentric coordinate system. The measurement range was plus or minus 6.4E4 nT.
