Triaxial Fluxgate Magnetometer

NSSDCA ID: 1959-014A-01

Mission Name: Luna 2
Principal Investigator:Mr. Sh. S. Dolginov


Ths space probe Luna 2 was instrumented with a three component fluxgate magnetometer similar to that used on Luna 1 but with the dynamic range reduced by a factor of 4 to -750 to +750 gammas so that the quantization uncertainty was -12 to +12 gammas. The spacecraft spin period was 840 sec about the major axis, and there was a precession with a period of 86 sec. The sampling rate of the instrument was approximately once per minute. According to the Principal Investigator, the errors associated with the experiment zero levels and spacecraft fields were such that the accuracy was approximately 50 to 100 gammas. The spacecraft gave results similar to those of Luna 1 in the earth's radiation belts and, upon impact, placed an upper limit of 100 gammas on the lunar magnetic field at the surface.
