TRANSFORMING THE WAY THE WORLD WORKS OVERVIEW Routescene designs and manufactures integrated 3D mapping solutions specifically for use on drones. Designed to survey sites where accurate mapping is essential but difficult to achieve, the system is perfect for hard to reach, dangerous or hostile environments such as landslides, steep slopes and densely vegetated areas. Achieving as high a level of accuracy as possible is required for such challenging applications and can be achieved using Trimble's products. Location Scotland, UK Colorado, US THE CHALLENGE A typical objective for any survey is to achieve a predetermined level of accuracy appropriate for the application and site being surveyed. Unlike static terrestrial surveys, a drone LiDAR survey is dynamic and requires a GNSS or inertial navigation system (INS) to determine its position and orientation; it is not as simple as mounting a LiDAR sensor underneath a drone. To meet this objective and quantify accuracy many factors have to be considered, such as the positional accuracy of the GNSS receiver, the angular accuracy of the INS and the angular accuracy of the LiDAR sensor. It's complicated! The rapidity of change - the position and orientation of the drone (Unmanned Aerial Vehicles or UAV) - changes every millisecond which compounds the problem. THE SOLUTION To design the perfect Routescene UAV LiDAR solution, the perfect blend of sensors were chosen. The individual accuracy of each sensor was considered to achieve the best overall accuracy possible for the system. The final UAV LiDAR solution consists of three main components: ► Routescene LidarPod ► Advanced Navigation Spatial Dual sensor ► Routescene Ground Station Routescene LidarPod® The 3D mapping instrument mounted underneath the drone, the Routescene LidarPod, is a state of the art Real Time Kinematic (RTK) GNSS and INS product which provides accurate position, velocity, acceleration and orientation under the most demanding conditions.
