About VFM

EFI

The Vector Field Magnetometer (VFM) is Swarm's core instrument. It makes high-precision measurements of the magnitude and direction of the magnetic field, i.e. the field's vector.

The VFM uses the proven fluxgate magnetometer design. VFM features a wide-range, high performance ring core fluxgate magnetometer. The fluxgate sensor uses the nonlinearity of magnetisation properties for the high permeability of easily saturated ferromagnetic alloys to serve as an indicator for the local field strength.

DATA TOOLS

VirES
VirES for Swarm, the virtual research service, is a highly interactive data manipulation and retrieval interface for Swarm constellation mission products. It includes tools for studying various geomagnetic models by comparing them to the Swarm satellite measurements at given space weather and ionospheric conditions.
