Abstract
The Automatic Identification System (AIS) uses a single GPS system and the accuracy of positioning is limited by the broadcast ephemeris, which is around 10 m. Thus, AIS is not competent for precise applications like ships in the crowded waterways. This contribution develops an improved navigation and warning system by integrating GPS and BeiDou satellite (BDS) together and calculating equivalent satellite clock errors of different constellation. Users can receive satellite clock corrections w.r.t broadcast ephemeris via Frequency Modulation (FM) or Very high Frequency (VHF) technology. The final result shows that accuracy of real-time positioning is within 1 m.
