The Guangdong Banting Survey Technology Co., Ltd. Collaborated with OceanAlpha, Beijing Zhuhai Putonghua and Ping DSP, and utilized Unmanned Surface Vehicles (USVs) equipped with Multibeam Sounding Systems and 3D Side Scan Sonars to conduct precise surveys in challenging water environments. From navigating dangerous sections beneath Longwan Bridge to exploring the depths of Taishan harbor basins, these unmanned solutions revolutionize maritime mapping, ensuring accuracy, efficiency, and safety. The project demonstrates the seamless integration of advanced equipment and software, such as Wave Master Navigation Systems and CARIS software, to enhance data collection, processing, and analysis.
