1、Leveraging Magnetic Drone Technology for Shallow Water UXO DetectionDr.Sara Lise Underhay,Sietse Bruinsma,Andries de Lange,Wouter Meinster,Ann-Christien Hohnke,Veronica Donadio+Many other Deeper Why Drones?Why Drones?Shallow water,intertidal areas and beach environments require magnetic UXO coverage

2、 These areas are difficult and time consuming to access with traditional methods Drone offers a safer,more efficient and consistent dataset.Goal of the surveyGoal of the survey Determine if horizontal and vertical configurations can be used successfully Determine limitations and required calibration

3、s for the system:Detection altitude(source-sensor separation)for each configuration Drone stability over water Calibration and speed requirements Positional accuracySensys R3 with SPH SkyHubTriaxial fluxgate sensors(Measure 3 vector components of the magnetic field)200Hz1.0mHorizontal Configuration1
