A GPS and Electronic Chart Based Maritime Positioning System for Searching and Rescuing Drowning People

摘要

With the rapid development of ocean shipping industry in China and the increasing of shipwreck occurrence, the higher requirements for maritime search and rescue are proposed. However, the current maritime search and rescue, depending on life jacket and searching in a large area, causes low efficiency. To solve this problem, this paper designed an intelligent maritime search and rescue system. The system integrates global positioning system (GPS), geographic information system (GIS), database synchronization and wireless transmission technologies. Test results show that the system guarantees the precise positioning of drowning people effectively and provides a reliable basis for rescue ships to search and track drowning people.
