Compound UV20

Four-in-One Inspections (UV + IR + EO + ToF)


The four-in-one payload (UV+UAV system) carries a UV sensor, an IR thermal imaging camera, a Zoom EO Camera, and a ToF sensor. Its UV sensor can detect ultraviolet sources, such as partial discharges or wildfires and has a consistent photon count value that guarantees that the readings in every inspection will always be consistent and unaffected, no matter the UV gain or zoom (within the operation distance, usually 15-20m ). It is also worth pointing that the camera is “blind” to the UV radiation coming from the sun, allowing only the relevant UV radiation to pass though the sensor.

Two measurements – one screen

The camera has two different modes in which it can display the UV radiation source: 1.UV + IR : Allowing thermal imaging 2.UV + EO: Allowing Zoom The UV sensor has a very high accuracy (with an error below 15%) and provides a consistent photon count value, displaying a very close approximation of the actual UV intensity value.


This ZQ product can detect UV sources, measure temperature and even measure the distance between the target and the payload. Therefore, providing an all-in-one solution that reduces the overall inspection workload.

Datasheet Compound UV20

Matrice 350 RTK

An upgraded flagship drone platform, the Matrice 350 RTK sets a new benchmark for the industry. This next-generation drone platform features an all-new video transmission system and control experience, a more efficient battery system, and more comprehensive safety features, as well as robust payload and expansion capabilities. It is fully powered to inject innovative strength into any aerial operation.

GPR system: Radar Systems Zond Aero LF (low frequency)

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 methane detector

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.
