Crane Ship Height Restriction Management System GPSkySafety (Maritime)
GPSkySafety (Maritime)
High-precision height management with centimeter-level accuracy using RTK-GNSS. Safe crane ship construction.
In construction around airports, managing the height restrictions of crane ship booms is essential for ensuring the safety of aircraft. GPSkySafety is a system that utilizes high-precision RTK-GNSS to safely conduct crane ship operations. 【Features】 ■ Centimeter-level height and position management using RTK-GNSS ■ Visual real-time display of restriction surfaces, current position and height, coastline maps, and layout diagrams ■ Alarm activation when height clearance falls below the set value ■ Ability to adapt to construction at various airports and facilities through changes in restriction settings

basic information
【System Overview】 The system automatically calculates in real-time the distance between the GNSS antenna located at the tip of the crane vessel (or construction crane) and the set limit surface. If known points are available, a GNSS reference station is set up to transmit correction signals via radio. In environments where a reference station cannot be established, network-based RTK-GNSS surveying can be conducted using VRS (Virtual Reference Station). Height and position accuracy can be managed within approximately 5.6 cm. On the crane vessel's bridge, the current height is visually displayed using dedicated PC software. Crew members use the height/clearance display on the screen as a reference for navigation and boom operation. When the boom tip approaches the height limit surface, an alert is issued through audio and screen display, providing a warning to the crew and supervisors.
