VFM Overview
... current that enables the sensor to detect minute deviations from the zero field. Noise on the instrument is only a few Picotesla while VFM provides a long-term stability in the sub Nanotesla range. The VFM is an analogue instrument and as such is subject to temporal changes due to radiation and the aging effect of electronics. The effects are only significant in the bias and linear scale parameters of the characterization; hence these parameters are estimated daily through a comparison of the VFM output with the Absolute Scalar Magnetometer output.
