Abstract

The invention discloses an integrity monitoring system for realizing an AIS differential data broadcasting system. The system comprises a base station completeness monitoring module, an observation data quality monitoring module, a system overall effectiveness monitoring module, a monitoring station and a data processing center module. The base station completeness monitoring module and the observation data quality monitoring module receive original data sent by a base station system through a BD / GPS antenna. The base station completeness monitoring module and the observation data quality monitoring module are connected to the system overall effectiveness monitoring module, the system overall effectiveness monitoring module is further connected with the monitoring station, and the monitoring station is connected with the data processing center module through an AIS broadcast network and a private network wired network. The long-time integrity statistical result of the original data isanalyzed, the time and space availability state of the system and the overall effectiveness of the system are monitored, the overall operation condition and availability of the ground-based augmentation system are evaluated, and whole-network precision monitoring can be carried out.

Description

technical field [0001] The invention relates to the technical field of satellite navigation differential data monitoring, in particular to an integrity monitoring system for realizing an AIS differential data broadcasting system. Background technique [0002] The positioning and navigation of the ship mainly depends on the satellite navigation system. The availability and real-time performance of the ship's position directly affect the decision-making of the ship's navigation and collision avoidance, which is related to the safety of navigation. The AIS differential data broadcast system provides high-precision positioning and navigation services through AIS real-time broadcast differential data, especially in areas with narrow channels and dense ships. It will be the main way to realize precise navigation of ships in the future, so It is very necessary for the integrity monitoring of the AIS broadcasting system. [0003] At present, in the integrity monitoring of the AIS b...
