Abstract

According to the transmission capacity currently provided by the Beidou-3 system, a data transmission system based on the Beidou-3 Navigation Satellite System (BDS-3) was designed to address the problems of the original data transmission of the hydro-meteorological observation system. The data transmission protocol was defined, and the data transmission message was composed of multi-minute observation data superimposed and encrypted by DES. The active self-reporting data transmission scheme and the interactive query data transmission scheme were elaborated. Data security is ensured by both data encryption and BDS-3 satellite communication; the data transmission message consists of multi-minute observation data overlay to ensure the arrival rate of real-time observation data; and the data integrity is ensured by the interactive query method.
