Abstract: A CubeSat magnetometer array system having a housing having CubeSat dimensions, a host computer, and a magnetometer array system. The magnetometer array system includes a circuit board mounted within the housing, a plurality of magnetometers operably mounted on the circuit board, and a microcontroller system operably coupled with the plurality of magnetometers. The microcontroller system is configured to synchronize data from the plurality of magnetometers, utilize machine learning processes to identify and reduce noise in the synchronized data, and output a signal representative of a magnetic field with reduced noise due to the machine learning processes. A communication interface is operably coupled with the host computer and the microcontroller system and configured to communicate the signal to the host computer.

Abstract: A system and method for separating spacecraft generated magnetic noise from geomagnetic field data includes detecting magnetic information using a plurality of magnetometers and outputting a representative detection signal, the magnetic information comprising magnetic noise and geomagnetic field data; receiving the representative detection signal including the magnetic information from the plurality of magnetometers and resolving the magnetic noise data and the geomagnetic field data by analyzing a relative gain and phase of the representative detection signal in a time-frequency (TF) domain, if a noise signal of the representative detection signal is sparse in the TF domain then the relative gain and phase is found using cluster analysis, and separating a geomagnetic field data signal from a magnetic noise data signal using cluster centroids in compressive sensing based on the cluster analysis.

Abstract: A magneto-inductive DC magnetometer is provided that is operable to output fluxgate quality measurements in a low mass, volume, power and cost package. The magnetometer enables constellation-class missions not only due to its low-resource requirements, but also due to its potential for commercial integrated circuit fabrication. In addition, the magnetometer will be part of a ground-based Space Weather Underground Citizen Science instrument package that enables dense arrays of space weather-relevant observations at mid-latitudes. The magneto-inductive operating principle is based on a simple resistance-inductor (RL) circuit and involves measurement of the time it takes to charge and discharge the inductor between an upper and lower threshold by means of a Schmitt trigger oscillator. This time is proportional to the inductance that in turn is proportional to the field strength.
