A set of submarine data recycling system was designed based on the Beidou satellite independently developed by China. The main control chip STM32L was responsible for controlling the working status. The communication positioning chip RD0538 collected and analyzed position information. Finally, the data to be transmitted back and the positioning data were transmitted through the Beidou first generation satellite. The test result showed that the positioning accuracy met the requirements for maritime use. The system had a simple structure and a small size, and the user could set the system transmission frequency.By reducing the power consumption, the system was able to extend its working time to 9 days.

Key words: Beidou satellite, short message, date recycling, low power, submerged buoy, satellite communications
