Ultra Light-Weight Potassium Magnetometer
GEM Systems developed the DRONEmag™ (GSMP-35U/25U) to be the first lightweight, high-sensitivity magnetometer specifically designed for UAVs. It has been installed and successfully tested on the Monarch Fixed-Wing Gradiometer, the GEM Copter Multi-Rotor UAV and the GEM Hawk Helicopter UAV. At a weight of less than 1 kg, this Ultra Light-Weight Sensor opens up new avenues for magnetometer surveys.
The sensors are based on GEM’s popular optically pumped Potassium Magnetometer sensor, which offers the highest sensitivity, absolute accuracy and gradient tolerance available in the industry. The 0.2 pT sensitivity potassium magnetometer forms the core of GEM’s UAV solutions.
The sensors stream RS-232 or RS-485 data which can be visualized for quality control purposes, the hardware is on board to facilitate a downlink of data. The GSMP-35U/25U magnetometer is also supplied complete with 128 Mb of onboard data storage, suitable for long flights.
The GSMP-35U/25U offers high-quality data at the highest sampling rate of up to 20 readings per second. It can be slung alone by a UAV or integrated into any UAV system such as our towed UAV AirBIRD and GradBIRD.
