Method for data subscribing and publishing in large scale CORS station broadcast system and device thereof

A satellite positioning field, a method for data subscribing and publishing in large scale CORS station broadcast system and device thereof are disclosed. In the process of data subscribing, publishing and establishing a connection, the whole broadcast system combines the subscribing, publishing and upstream and downstream data management together, shields the specific machine information, the users only need to care about what data they need, the system framework itself flexibly establishes the connection with the upstream work node according to the route selection strategy, which facilitates the serialization and management of the upstream and downstream modules, saves the cost of repeated development.
