Mission Name: Explorer 12This experiment was designed to measure the magnitude and direction of the earth's magnetic field between 3 and 13 earth radii. It consisted of three orthogonal fluxgate magnetometers mounted on the end of an 86.4-cm boom. One magnetometer axis was within 2 deg of the spacecraft spin axis. Each of the three sensors had a range of -1000 to +1000 nT with a digitization uncertainty of 12 nT. The three components of the magnetic field were all measured within a 50-ms time period once every 327 ms. An inflight calibration system applied a known magnetic field to each sensor in turn once every 115 s. This experiment performed normally from launch through December 6, 1961.
