Abstract

The invention discloses a Beidou foundation enhancement system covering the trunk line of the Yangtze River and a construction method. The Beidou foundation enhancement system comprises a base stationsubsystem, a broadcasting station subsystem, an integrity monitoring subsystem, a data processing subsystem, an equipment monitoring subsystem, a network transmission subsystem and a support guarantee subsystem. According to the invention, a reference station network reasonably distributed in the Yangtze River trunk line area is constructed so thatobservation data of Beidou satellite data information is obtained. Data deviation observation information within a certain period of time is obtained to provide basic data for eliminating interference of ionized layers and tropospheric layers on satellite signals, an AIS broadcasting station is constructed, Beidou differential positioning service is provided for Yangtze River inland river sailing ships, RTK data service is provided through a private network or a public network, and Beidou differential positioning service is provided for the Yangtze River inland river sailing ships. The system meets the requirements of different levels, monitors the integrity of the system, monitors the overall effectiveness and availability of the system and the precision of the whole network, and has an alarm function, thereby guaranteeing that reliabledifferential positioning information is provided for a user.

Description

technical field [0001] The invention relates to the technical field of satellite navigation systems, in particular to a Beidou ground-based augmentation system covering the trunk line of the Yangtze River and a construction method thereof. Background technique [0002] Enhanced system differential information playback modes include user interaction mode and real-time broadcast mode. At present, the Beidou enhancement system that has been built or is under construction mainly uses the user interaction mode of 3G / 4G wireless network or wireless broadband network based on the public network. However, in the field of marine navigation applications, real-time broadcasting is mainly used. my country's coast adopts the medium frequency radio broadcasting method, and the RBN-DGPS broadcasting system has been built, and is being changed from DGPS single-mode to DBS / DGPS dual-mode system. Considering the types of ships on the Yangtze River, the equipment requirements of different sh...
