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.
