Instrument details
Acronym PWE
Full name Plasma Wave Experiment
Purpose Measurement of the electric field and its oscillations along the satellite HEO cross the magnetosphere
Short description Detailed description not yet available. Presumably, electrometer covering the dynamic range 0.1-1000 mV/m for oscillations in the frequency range from 1 Hz to 10 MHz
Background Companion of the Magnetic field experiment (MGF) 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
Mass Power Data Rate
