Design and Implementation of Marine Environmental Information Observation System Based on UUV

A marine environmental information observation system based on UUV was designed and implemented to overcome the deficiency of marine environment observation mode through surface ship which is severely affected by the marine environment, unable to observe snugly and near sea bottom. This system comprises surface support subsystem and UUV subsystem, may navigate according to a pre-loaded mission plan and at the same time, can observe the planned marine environment information. The results of Qiandao lake experiments showed that the UUV system realized to observe the temperature, salinity, depth, current profile and submarine topography and geomorphology in predetermined water region. And the post processing results are consentaneous with the lake actual information. It indicates that the observational data are accurate, authentic and trustworthy.
