April 2012, the very first UAV Lidar test was held in Weifang, Shandong Province, China. After thorough discussion and preparation with the help of the UAV helicopter company, we tested a series of functions of GL-300 Lidar system. The test was carried out with different flying height, flying speed with different Lidar system settings, to verify the system stability, performance and data accuracy. Testing result was excellent and all testing purpose was fulfilled.
