The Astrid-2 Satellite Magnetometer Used For Earth's Magnetic Main Field Modelling
Abstract
The data acquired by the Astrid-2 micro-satellite magnetometer has been used to de- termine the model of the Earth's Magnetic field. The satellite was designed for the investigation of the Aurora. However, the magnetic instrument was able to measure the scalar intesity of the field and the fitting to a magnetic model was possible with a misfit of less than 5nT. The satellite was injected into a polar orbit on December 1998 at 1000 km of altitude. The orbit characteristics and the significant quality of the magnetic measurement opens the prospects for inexpensive geomagnetic missions.
