DGNSS Integrity Monitor system based on AIS

摘要

The invention error correction integrity of information generated in the AIS unit of AIS virtual reference station-based reference station system relates to the AIS-based DGNSS integrity monitoring system to monitor, is connected to the DGPS reference station which transmits a satellite error information via the network, receiving the error information satellite and generates the error correction information from the satellite information received by the transmission error and AIS virtual reference station equipment; And AIS base station apparatus for transmitting and receiving the error correction information to be sent from the AIS virtual reference station apparatus; GNSS receiver for monitoring the integrity of the comparison, and AIS terminal for receiving error correction information to be sent from the base station AIS device, error correction information of the received information of the GNSS receiver and the AIS terminal after determining whether the integrity of the error correction information AIS wherein the integrity information in accordance with the determined integrity monitoring system-part for feedback to the virtual reference station integrity monitoring device; and a This invention does not need to be equipped with a DGPS beacon receiver AIS equipped vessel is effectively possible to provide more improved DGPS correction information services, can be more accurate trajectory tracking and monitoring marine vessels and, through the improved positional accuracy of the vessel Ship collision prevention, accident analysis contributes to the ship and ship control, such as maritime traffic safety. ;
