Instrument details
Acronym
MGF (ERG)
Full name
Magnetic field experiment
Purpose
Measurement of the magnetic field along the satellite HEO cross the magnetosphere
Short description
Detailed description not yet available. Presumably, vector magnetometer covering the dynamic range +/-65,536 nT with a resolution of 1 nT @ maximum of the dynamic range
Background
Companion of the Plasma Wave Experiment (PWE) on ERG
Scanning Technique
Volumetric exploration of the magnetosphere as the satellite travels along the HEO with perigee 300 km and apogee 30,000 km whilst spinning at 1 round / 8 s
Resolution
