from Geometrics

The MagArrow is a high performance magnetometer specifically designed for deployment on Unmanned Aerial Vehicles (UAV). At the heart of the system is Geometrics latest MFAM laser pumped atomic magnetometer with 1000Hz sample rate. The sensor is completely self contained with internal GNSS and IMU for precise measurement timing and measurement compensation respectively. The low power MFAM sensor allows the system to run for up to 2 hours on a single 1800mAh battery. Batteries can be hot swapped in a couple of minutes ensuring the UAV can remain airborne, alternatively the MagArrow can be powered from an external power source for extended operations.
