KEEL has a max. payload of 10kg and a max. flight time of 120 minutes. With a 5kg payload, it can fly for 60 minutes (classic version). This model is equipped with an integrated land and underwater terrain scanning lidar, designed for drone-based aerial imaging, covering various water bodies such as coastlines, rivers, lakes, estuaries, ponds, and gravel pits. The lidar weighs 3.7kg (without battery), has a max. AGL of 100m, and a system accuracy of 3cm. One-touch start allows the system to autonomously collect data, supporting satellite-based differential RTX, eliminating the need for a base station worldwide. Multiple echo technology provides more detailed ground object detection. One-touch track correction generates a visual 3D point cloud, independent of the laser sensor manufacturer's pre-processing software. An integrated high-precision positioning and attitude determination system ensures high-precision results. It is suitable for a variety of applications, from hydrographic surveying to underwater resource management.
