Research on the GNSS Augmentation System Based on the AIS

摘要

At present, the Global Navigation Satellite System (GNSS) has become an important satellite navigation system in the maritime domain. In order to guarantee marine navigation safety, the GNSS augmentation system based on the automatic identification system (AIS) is presented, and the basic system structure of two solutions and transport mechanisms of differential augmentation information are given in this paper. The experimental results show that the developed system can greatly improve the positioning accuracy of offshore moving vehicles to enhance marine navigation safety.
