Abstract
The paper discusses the design and development
of a Fluxgate Magnetometer, for use in space for Attitude
Determination and Control (ADC) of Low Earth Orbits (LEO)
satellites. The designed sensor consists of two coils, drive and
sense and is based upon the principle of mutual induction. A
toroidal core based design was finalized and fabricated on
which the drive and sense coil are coupled. Three different
design approaches were adopted. Overview of these designs is
discussed with detailed discussion on the most promising
design. The developed sensor has the resolution better than
200nT. Results achieved are quite stable and the response of
the sensor is in the range of ±50000nT. The results achieved
are quite similar as predicted by simulations of overlapped
waveforms.
