The LR-D1 Pro is the more robust version of the latest generation of our long-range radar altimeter. It employs a 60 GHz antenna for centimeter-level precision at low altitudes and a 24 GHz antenna for enhanced capabilities at high altitudes. Like the LR-D1, it provides accuracy in all environments and weather conditions, even under the most adverse and low-visibility scenarios. The LR-D1 Pro is ideal for larger UAVs (85kg+) performing VTOL, helicopters, and for mission-critical tactical applications that require increased precision and ruggedized durability.
