Single Axis Search-Coil Magnetometer

NSSDCA ID: 1958-007A-02

Mission Name: Pioneer 1
Principal Investigator:Dr. Charles P. Sonett

Description

This magnetometer was designed to study the magnetic field between the earth and the moon and to test for a lunar magnetic field. Due to a launch vehicle malfunction, it was used to study the geomagnetic field along the trajectory. The magnetometer was a single search coil designed to measure the component of the magnetic field perpendicular to the spin axis. The returned signal was digitized at 52 samples per sec. The magnetometer had a range of 6 microgauss to 12 milligauss. No inflight calibration was provided between 0945 and 1106 UT and between 1543 and 1719 UT when the spacecraft was at radial distances of 3.7 to 7.0 and 12.3 to 14.8 earth radii. The experiment is described in detail by Sonett, JGR, vol 67, p 1191, 1962.
