QUEBEC CITY, CANADA, February 25, 2016 – LeddarOne, the novel optical range finder from LeddarTech that was recently introduced for drone altimetry applications, is now being offered at the affordable price of $115. Rapidly growing demand in the unamanned aircraft systems (UAS) market for highly reliable height-above-ground measurement sensors that feature the patented Leddar technology has motivated the reduced pricing structure, a clear indication of LeddarTech’s strong commitment to supporting this industry’s rapid evolution.

“The initial success of LeddarOne for drones allows us to generate increasing volumes and deliver the popular sensor module with the same great features and performance levels at lower price points, which will undoubtedly appeal to both large UAS manufacturers and specialized integrators alike,” said Luc Langlois, Vice-President Marketing at LeddarTech.

LeddarOne optical altimeters measure the backscattered signal from infrared light pulses to deliver fast and highly accurate height-above-ground-level (AGL) measurements, which fulfill the drone market’s stringent requirements for takeoff and landing applications as well as in-flight height AGL measurements—both outdoors and indoors.

The compact, lightweight sensor modules leverage Leddar’s unmatched cost-performance ratio to deliver a larger detection zone, better sensitivity, and increased accuracy, compared with competing solutions, over the full range of operating conditions (temperature, ambient light, and weather).

The LeddarOne benefits from the same unique Leddar signal processing algorithms being implemented in the automotive sector as well as in a variety of other applications, which span from cinematography auto-focus devices to highway speed enforcement systems.

LeddarOne sensor modules are available for purchase immediately from the RobotShop online store as well as from the LeddarTech website.
