2.3.1 spase://CNES/Instrument/CDPP-AMDA/Pioneer10/MAG MAG 2009-05-20T21:10:15Z The magnetometer on Pioneer 10 (also carried on Pioneer 11) is a triaxial helium magnetometer with seven dynamic ranges, from plus or minus 2.5 nT to plus or minus 10 gauss. The linearity was 0.1%, and the noise threshold was 0.01% rms for 0-1 Hz. The accuracy was 0.5% of full scale range. The experiment worked as planned until November 1975, when the spacecraft was at about 8 au. No further useful data were obtained. The experimenter has used RTN coordinates in his data analysis. In this system, R (or X) is radially outward from the sun, T (or Y) is parallel to the sun's equatorial plane and has its direction given by the cross product of the sun's spin vector into the radial direction (i.e., into R) and N (or Z) completes the right-handed orthogonal system (positive northward). A detailed instrument description may be found in Smith et al., IEEE Trans. On Magnetics, Mag-11, p. 962, July 1975. Some data also include the interplanetary region. This instrument failed in October 1975 and was turned off in June 1986. spase://SMWG/Person/Edward.J.Smith PrincipalInvestigator NSSDC's Master Catalog http://nssdc.gsfc.nasa.gov/database/MasterCatalog?sc=1972-012A&ex=1 Information about the Magnetic Fields experiment on the Pioneer 10 mission.
