A System for Measuring Vector Magnetic Fields from Sounding Rockets

摘要

Tests of a newly designed operational system show that the earth's vector magnetic field can be measured from a sounding-rocket nose cone by (a) determining the attitude of a rocket nose cone by means of an electromagnetic attitude-sensor using antenna-array signal-strength patterns; (b) making vector magnetic measurements within the rocket nose cone by means of switched bias coils and a cesium vapor magnetometer; (c) encoding and telemetering the resulting information in a format compatible with the existing facilities; and (d) developing computational techniques for reducing the data obtained from the system.
