BackForwardInstrument:  MGF (ERG) 

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 N/A
Coverage / Cycle Full magnetospheric volume, more frequently in low-middle latitudes, consistently with the 31° orbital inclination
