Comprehensive Magnetic Noise Suppression Methods for Small Unmanned Aerial Vehicles

To support the Navy's requirements for low-noise magnetic sensing from small unmanned aerial vehicles (UAVs), we present effective methods for suppressing platform and external interferences. We propose to develop a comprehensive magnetic compensation system that heavily leverages a number of innovations, experience, and on-going work by our team. Our approach combines thorough characterizations of candidate Tier I and/or Tier II UAVs with full-spectrum noise cancellation algorithms and miniaturized sensor and electronics amenable to future installation on in-service unmanned Navy assets. The resulting technology will maximize the potential use of advanced implementations of digital filtering and compensation software fed by new chip-scale vector magnetic sensors.
