BackForwardInstrument:  MAG (Solar Orbiter) 

Instrument details
Acronym MAG (Solar Orbiter)
Full name Magnetometer (Solar Orbiter)
Purpose To provide in-situ measurements of the heliospheric magnetic field with high precision. This will facilitate detailed studies into the way the Sun’s magnetic field links into space and evolves over the solar cycle; how particles are accelerated and propagate around the Solar System, including to the Earth; how the corona and solar wind are heated and accelerated
Short description Assemblage of two digital fluxgate sensors operated in the dual-magnetometer mode (both in shadow and mounted on the instrument boom behind the spacecraft body). Missing details on the characteristics. Presumably, 8 dynamic ranges: ± 4 nT; ± 16 nT; ± 64 nT; ± 256 nT; ± 1024 nT; ± 4096 nT; ± 16,384 nT; and ± 65,536 nT. Resolution ± 16 nT @ maximum of dynamics. Accuracy 0.006 nT
Background Consolidated technology
Scanning Technique Sun pointing from the L1 Lagrange libration point
Resolution N/A
Coverage / Cycle Full solar disk, sampling at 0.09 s intervals
