Magnetic gradiometry using frequency-domain filtering

Russell, Christopher T.; Raymond, Carol A.; Polanskey, Carol A. +7 more

Accurate measurements of ambient planetary and interplanetary magnetic fields using spacecraft magnetometers typically require accounting for interfering magnetic fields generated by the flight system (FS). The most common method for removing FS-generated time-variable magnetic fields is narrow-band and low-pass filtering of magnetic field data in…
