| Zusammenfassung |
| We present the first in-flight results from a novel miniaturised anisotropic
magnetoresistive space magnetometer, MAGIC (MAGnetometer from Imperial
College), aboard the first CINEMA (CubeSat for Ions, Neutrals, Electrons
and MAgnetic fields) spacecraft in low Earth orbit. An attitude-independent
calibration technique is detailed using the International Geomagnetic
Reference Field (IGRF), which is temperature dependent in the case of the
outboard sensor. We show that the sensors accurately measure
the expected absolute field to within 2% in attitude mode and 1%
in science mode. Using a simple method we are able to estimate the
spacecraft's attitude using the magnetometer only, thus characterising
CINEMA's spin, precession and nutation. Finally, we show that the
outboard sensor is capable of detecting transient physical signals
with amplitudes of ~ 20–60 nT. These include field-aligned currents
at the auroral oval, qualitatively similar to previous observations,
which agree in location with measurements from the DMSP
(Defense Meteorological Satellite Program) and POES
(Polar-orbiting Operational Environmental Satellites) spacecraft.
Thus, we demonstrate and discuss the potential science capabilities
of the MAGIC instrument onboard a CubeSat platform. |
