Abstract:Abstract As an irreplaceable high-tech advanced equipment and emerging equipment for ocean observation exploration, marine unmanned autonomous observation equipment is the pioneer of new life and new fields in the cradle of ocean observation exploration equipment. Improving ocean mobile observation capabilities based on marine unmanned observation equipment is an important technical means for building a three-dimensional, continuous, and real-time underwater observation network in the future. The development and use of marine unmanned autonomous observation equipment will profoundly affect the way of ocean observation and exploration in the future. Based on the analysis of the development and application status of marine unmanned observation equipment at home and abroad, this paper considered the main problems and gaps in the development of our country’s marine unmanned observing equipment, and prospected the future development and application of marine unmanned observing equipment .
