Miniature Oriented Tri-Axial Fluxgate Magnetometer Sensor, Phase II

Technology advances have produced a class of unmanned vehicles (UVs) that operate in air, on the ground, and underwater. These platforms are ideal for remote sensing because they are small, lightweight, fast, and covert. There is ongoing interest in integrating SIGINT sensor packages onto these platforms.One disadvantage to these small platforms is that they are easily buffeted about by environmental conditions (waves, wind, etc.), and this presents a challenge to low frequency electromagnetic (EM) sensors. This motion-induced signal becomes clutter, or noise, in the data, which overwhelms signals of interest.There is a need for high sensitivity, low frequency magnetic sensors for long range SIGINT on UVs. These sensors must have motion isolation and large dynamic range to sense small long-range signals atop large motion-induced signals. QUASAR Federal Systems (QFS) is a world leader in advanced electromagnetic sensing. That expertise includes a patent for an integrated, 3-axis, fluxgate/induction sensor. QFS leveraged its expertise in Phase I to determine system specs and noise cancellation methods for a 3-axis fluxgate sensor. In this proposed Phase II base + option project, QFS will build the sensor, implement noise and motion cancellation, and test the prototype in a marine environment.
