Acronym
IMPACT/MAG
Full name
IMPACT / Magnetometer
Purpose
Observation of the vectorial magnetic field in the vicinity of the Sun
Short description
Triaxial fluxgate sensors, mounted on booms. Description not available. Presumably, triaxial fluxgate magnetometers (boom mounted). 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
