Short summary
Measurements from the magnetic field instrument on the Cassiope spacecraft were found to be degraded by an artifact of how the instrument tracks the changing magnetic field as the spacecraft orbits the Earth. We present a process to characterize this effect on orbit and compensate for it in the post–processing of the data. This work allows the instrument to accurately track rapidly changing local fields without loss of measurement fidelity and improves the high–frequency noise of the data.
