In order to maximize flexibility, duration and velocity weight must be kept at minimum. micROM HD is a lightweight camera with energy-efficient management allowing longer, higher and faster flights while scanning power lines. micROM HD silhouette simplifies the outline of gimbal design requirements.
micROM HD streams & records HD videos providing clear views of the inspected scenes, allowing reading plate names & catalogue numbers of equipment for maintenance referencing. Videos can include corona events count, date & time, GPS, temperature and humidity (optional). High resolution guarantees more observed detailed data.
micROM HD provides in real time the representation of corona as it is emitted, displaying both the discharges and the faults. Imagery is clear and sharp even while on the move. Output is used to determine faults’ location and level of severity.
“As of Aug 2019, SDG&E is the first company in the United States to fly the corona camera on the UAS with the support of a local vendor integrating the camera on a UAS. In recent work, SDG&E completed 5 successful test flights on August 19- 20, 2019 and again on September 12, 2019 and assessed twelve 230kV tower structures, which took approximately one and half hours to complete. The normal way for this inspection is to use a handheld corona camera and that would have taken four hours. More testing is scheduled for 2020, and efforts will be made to integrate the procedures into the regular workforce operations.”

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.
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.
EchoLogger ECT 400S echo sounder with tilt and temperature sensor, harness, housing, and mountings for the drone.
