Outperforms foot search by 5x times
Detected leaks are referenced to GPS coordinates (high fidelity RTK GPS is also supported)
Applicable at unsafe and hazardous environments without compromising the safety of staff or equipment
Fully automated and repeatable surveys
Laser detector LMm is sensitive only to methane, so no false readings of other gases are possible
Fully automated reporting
> Mount the methane-leak-detection kit onto the drone
> Plan survey mission with UgCS
> Receive data during flight
> Generate a report with detected methane leak locations
The system consists of the drone integrated with laser methane detector LMm by PERGAM. The full integration is ensured by adding the onboard UgCS data logger to the system.

Customer: Conexus Baltic Grid, JSC
Goal: Locate methane leaks.
Technology: integrated Laser Methane detector by PERGAM with a drone equipped with a laser altimeter.
Flight control: UgCS with True Terrain Following mode.
Result: Methane leaks can be located during the drone's inspection flight. Methane level data is being logged with precise GPS coordinates of drone's autopilot.
Laser Methane Detector by PERGAM 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. Laser light in the spectral range of 1,65 μm is emitted. The laser light is reflected in the background and captured back in the instrument. The outgoing and incoming signals are compared with a built-in reference cell. If methane gas 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.
UgCS Data Logger is the key element that enables the full integration of the drone, laser methane detector, and ground control software UgCS. The onboard UgCS Data Logger, designed by SPH Engineering, saves the gas detector’s data in .txt format and transfers them instantly to the remote control of the drone pilot and to the desktop software UgCS. This allows operators to detect leaks in real time and ensure faster response time.
The UgCS Data Logger enables also to add a laser altimeter to enable the flight in True Terrain Following mode, which enables the drone (UAV) to accurately follow the terrain during the flight, based on data received from the laser altimeter. True Terrain Following enables the drone to fly at constant AGL altitude without a need to import precise Digital Elevation Model (DEM) height-map into UgCS.
Currently, the UgCS Data Logger is compatible with off-the-shelf or custom-built UAV based on DJI A3 flight controller, i.e. DJI M600 / M600 Pro and DJI DJI M210 / M210 v2
The DJI M600 and M600 Pro is a durable system that offers extended flight time (up to 25 minutes) and a 5-kilometer-long range of data transmission.
Smooth operation is ensured by UgCS software, developed by SPH Engineering in Riga, Latvia. Besides supporting most industrial drones on the market, it offers several productivity-enhancing innovations: automatic Photogrammetry, Facade scan, and Search pattern tools. Most importantly for methane detection, UgCS software allows for the drone to be flown at a constant height, even over rough and mountainous areas, as its 3D maps and terrain-following mode can cope with any kind of landscape. UgCS's drone mission planning software also provides tools for the easy creation and calculation of flight paths, and for the interpretation of acquired data in a user-friendly manner.
