Fluxgate Magnetometer

NSSDCA ID: 1969-097A-01

Mission Name: Azur
Principal Investigator:Dr. Guenter Musmann


A two-component fluxgate magnetometer with two identical electrically independent measuring units was used as an attitude sensor and as an experiment for detecting transverse hydromagnetic waves. It was oriented perpendicular to the magnetic field. In order to eliminate magnetic fields from the satellite, the magnetometer was placed on a boom about 80 cm long. The sensor was to be thermally shielded by a cylindrical metal cap. Each sensor had a range of minus to plus 1.E4 nT, with 4.8-nT digitization resolution. Each sensor was sampled for 125 ms once every 5 s. The experiment worked normally until the spacecraft telemetry system malfunctioned in early July 1970. For further details, see B. Theile and H. M. Praetorius, "Field aligned currents between 400 and 3000 km in auroral and polar latitudes," Planet. Space Sci., v. 21, pp. 179-187, February 1973.
