Spacecraft (S/C) magnetic stray fields and Sun induced stray field at VFM sensor position
Thematic areas: Magnetic measurements
Applicable missions: Swarm
Applicable spacecraft: Swarm-A, Swarm-B, Swarm-C
The VFMxAUX_1B Product contains detailed information on the S/C magnetic stray fields and the Sun induced stray field at the VFM sensor position. The data are provided at 50 Hz at the time-instants of the VFM measurements; the stray field vectors are provided in the VFM sensor frame.
