MagArrow Applications


Find abandoned wells, pipes, and storage tanks quickly and with precise positioning.


Survey vast distances and leave potential archaeology sites undisturbed with the MagArrow.


Survey for regional variations in the magnetic field with the MagArrow.

UXO Detection

Flying at high speed with a fast sample rate, MagArrow is the perfect tool to survey sites for detection and delineation of UXO.

Why Using MagArrow

Reach Inaccessible Terrain

Thanks to high sensitivity, difficult of dangerous terrain is no problem for the MagArrow, making it perfect for surveying wetlands, heavily vegetated areas, extreme terrain, or protected lands

Super-Fast Sampling Rate (1000Hz)

Fly faster, up to 10 m/s with samples every 1 cm. Filter out UAV motor noise

Low Battery Consumption

A single 1800 mAh lithium polymer battery will power the system for 2 hours, outlasting multiple UAV flights. Batteries are hot-swappable


Weighs only 1 kg, allowing a long flight time for typical drones like DJI M600 Pro

UAS Agnostic

Attachable to most enterprise UASs


GPS, storage, and WiFi on board. No data connections to UAV needed

How it Works

The system consists of the MagArrow magnetometer mounted on a drone. Survey missions are planned and flown in automatic mode with UgCS. The adding of the onboard computer UgCS SkyHub enables the drone to fly in True Terrain Following (TTF) mode with the help of the radar altimeter and logs precise flight track to refine MagArrow's data.
