      <Description>The Mars Global Surveyor magnetic field instrument consists of
        dual, triaxial fluxgate magnetometers, capable of measuring fields
        between +/- 4 nT and +/- 65536 nT. Automated range switching allows
        the instrument to maintain maximum digital resolution over a wide
        range of field strengths.
