UXO Detection

UXO Drone Detection Technologies

Detection of UXO is an expensive process, so any method to help safely speed detection benefits the specialists who deploy latest technology. 

We specialise in UXO detection and offer a range of UXO detection drone systems. Request our detailed spec sheets so we can advise best solutions per specific applications. CONTACT for DETAILS

Some of the systems we offer:

SENSYS MagDrone is a Fluxgate magnetometer system and therefore is able to detect any magnetic metals/materials.

It is applicable to:

- Searching for UXO (unexploded ordnance)
- Locating buried infrastructure (metal pipes and shielded cables)
- Archaeology
- Surveying for any metal objects weighing a few hundred grams or heavier lying underground

The integrated system combines a drone with a sensitive magnetometer SENSYS MagDrone R3 and a precise altimeter for True Terrain Following mode.


Using a magnetometer on a drone enables us to scan the area and detect metals several times faster compared with handheld devices and allows obtaining geo-referenced maps of the area. Safety is also a factor, remote operation speeds the detection process. Digital records detail precise coordinates.

We also supply the MagArrow


Ultra-sensitive hi-end lightweight magnetometer for UAV


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

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

Geology: 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 use 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

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

UAS Agnostic: Attachable to most enterprise UASs

Self-Contained: GPS, storage, and WiFi on board. No data connections to UAV needed


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.

UAV: DJI M600Pro or similar

UgCS SkyHub: Manages True Terrain Following mode and logs precise flight track

UgCS: Drone mission planning and flight control software for challenging conditions

Altimeter: Precise radar altimeter to fly automatically in True Terrain Following (TTF) mode



Goal: to detect metallic items on the bottom/under bottom of the lake. Technology: MagArrow integrated with a drone equipped with a radar altimeter.
Flight Control: UgCS with True Terrain Following mode.

Specialist Equipments:

To achieve good results, and for the safety of the drone, it is vital to control precise low altitude over the ground surface. For the metal detector recommended flight altitude is 0.5...1.0 m between sensor coil and the ground. We use a high-frequency radar altimeter with precision 2cm and a special terrain-following algorithm to keep the altitude of the drone constant during automatic survey missions.

On-board computer

The heart of the integrated system is UgCS SkyHub – a small and powerful onboard computer with special software. 

The first function of this onboard computer is to maintain a constant altitude of the drone over the surface using data from the radar altimeter. Standard DJI drones do not have such function and rely on a barometric altimeter for altitude control. Unfortunately, it is not a precise sensor and altitude drift per single flight can be up to several meters.

The second function of the onboard computer is to store metal detector measurements in geotagged form. To geotag data, the UAV’s GPS receiver is used. If the drone is equipped with an RTK/PPK receiver, data points will have coordinates with precision down to centimeters.

Measurements are stored in simple textual CSV format with coordinates allowing the import to a variety of software capable to process XYZ data (Surfer, Oasis Montaj).

Data logging begins automatically after take-off and stops after landing.
