The Application of Beidou Satellite Communication in Drifting Buoys

摘要

A sea surface drifting buoy system based on Beidou communication system is designed and developed by Institute of Oceanology, Chinese Academy of Sciences. It employs a low power consumption chip, STM32F103RCT6, as the core of the control system, which can collect and process the data of the ocean environment automatically and monitor the status of the buoy system. Then the marine data are transferred to the lab on shore in real time by Beidou satellite. With the power management function, this system will reduce system power consumption greatly and extend the working time of the buoy. By placing and using the buoy at sea, the feasibility and reliability of this system is verified, which has provided the reliability support of acquiring some real-time elements and track currents of the ocean current in some certain sea area in long time real-time access to the sea currents.
