Patent number: 11305854Abstract: A deep-sea low-cost long-endurance collaborative navigation and positioning system. A shore-based monitoring center transmits a route planning solution to a wave glider. The wave glider follows an underwater vehicle to travel and feeds back state information of the wave glider and state information of the underwater vehicle to the shore-based monitoring center in real time. The shore-based monitoring center adjusts the route planning solution according to the state information in real time. The wave glider and the underwater vehicle are respectively equipped with an underwater acoustic communication machine.Type: GrantFiled: April 15, 2020Date of Patent: April 19, 2022Assignees: NATIONAL DEEP SEA CENTER, QINGDAO NATIONAL LABORATORY FOR MARINE SCIENCE AND TECHNOLOGY DEVELOPMENT CENTER, TECHNOLOGY DEVELOPMENT CENTERInventors: Tongwei Zhang, Guangjie Han, Lei Yan, Haibing Li, Xiujun Sun, Shuai Zhang, Jingxiao Liu, Lei Yang
