EARTH MAGNETIC FIELD MODEL FOR SATELLITE NAVIGATION AT EQUATORIAL VICINITY
Keywords:
Geomagnetic field modelling, WMM2005 model, satellite attitude determinationAbstract
This paper presents the determination ofthe most suitable onboard magnetic field
model for the navigation of a satellite near the equatorial orbit. This onboard
model is derived from the World Magnetic Model of the year 2005 (WMM2005)
and the criterion ofthe selection is to optimize magnetometer measurements from
the satellite navigation system. For that purpose several scenarios differing by the
degree ofthe field model used are considered and analysed. Taking into account
the amplitude ofthe magnetic disturbances onboard ofthe satellite, the best model
is determined.
