Adaptive Interference Cancelation using a Pair of Magnetometers for Small Satellite Applications: No Need for a Boom

Abstract:

We have developed a new method for adaptively canceling a magnetic interference using a pair of magnetometers, which is especially effective for a time-varying interference with an unknown signature. By canceling the interference, the method enables the recovery of the ambient geomagnetic field. Computer simulations and experiments with real-world data validate the theoretical analysis, and thereby, pave the way for magnetic measurements in orbit using boomless CubeSats.
