Abstract
Drone-based magnetometer systems provide the ability to measure and analyze magnetic fields in a moving vessel that is able to efficiently move through space. Currently, most drone-based magnetometer systems require the use of an extension system like a wire or a rod to move the magnetometer away from the drone’s frame to prevent interference from the drone’s electromagnetic field (EMF) on its measurements. In this project, we aim to find a method where the magnetometer can be directly mounted on the drone by dynamically filtering out the drone’s EMF, removing the need for a complex extension system. We use and build upon existing measurement programs for calibrating a modified quad-magnetometer to filter out the EMF of the drone’s motors, battery, and electronics. This is done by conducting numerous trials testing the magnetometer’s sensor outputs from distinct locations near each of the drone’s motors while it’s running to aid in the development of an algorithm that could filter out these signals. We will then test the drone in flight with the calibrated magnetometer system directly attached and understand the effectiveness of our method. We hope to find that this method provides a simpler and more aerodynamic implementation of a drone-based magnetometer for future systems. These findings can be built upon to develop more accurate algorithms and more efficient hardware implementations, allowing for broader applications in fields such as geological surveying, archaeology, navigation, and environmental monitoring.
