The MagArrow is engineered to simplify surveys that are difficult due to the various limitations of pilot-on-board surveys and ground surveys. The MagArrow is a robust yet flexible system that can adapt to changing field conditions and new user workflows. The MagArrow consists of an aerodynamic, light-weight carbon fiber shell with internal electronics including the MFAM™ magnetic sensors, GPS, and IMU. The MFAM™, a two sensor module inside the MagArrow is our most groundbreaking magnetometer yet, capable of highly precise measurements in an extremely lightweight and tiny package.
MagArrow is fully self-contained sensor (with build-in GPS receiver, data recorder and battery), and may be used with any suitable UAV suitable to carry 1kg.
To minimise noises from drone’s motors and electronics, it is recommended to use 3m long suspension ropes to mount MagArrow under the drone. For such configuration it is recommended to use larger drones as DJI M600 Pro or similar, with smaller drones (DJI M300 RTK, etc.) we recommend to use extention poles for the drone’s legs.
Alternative way is to mount MagArrow right on the legs of drone and use low-pass filter during data post-processing to remove drone’s noises. That approach works pretty well for the surveys like UXO search, but for work requires to register weak or long anomalies (archaeology, geology, etc.) it is better to use suspension ropes.
Note, that general rule with magnetometer when it is necessary to detect artificial objects or artefacts – fly as alow as possible. Recommended altitude for the tasks like UXO search – 1m above surface or even lower. That means that drone should be equipped with terrain following system (included in recommended magnetometer bundle).

A safe, efficient, and accurate way to obtain 3D nuclear radiation dose rate distribution. Assess the scene from a safer distance.
Extra-lightweight GPR system, suitable for medium-sized drones like DJI M300 RTK.
Comes with 3x sets of dipoles for the 300, 150, and 100 MHz.
Utilizes Real Time Sampling (RTS) with high hardware stacking, delivering high-resolution low-noise data.
Laser Falcon is sensitive only to methane, so no false readings of other gases are possible. It is a class 3R eye-safe laser.
The concept is based on Infrared Absorption Spectroscopy. The laser emits light (spectral range of 1,65 μm), which reflects back and is captured by the sensor. The outgoing and incoming signals are compared with the built-in reference cell. If methane is present along the laser path, the laser light is partially absorbed. An algorithm calculates the gas concentration in ppm×m (parts per million multiplied by meter). The value is instantly transferred to the remote control (RC) of the drone pilot and to UgCS software.
