Description

technical field [0001] The invention relates to the technical field of multi-point positioning, in particular to a data output processing method and system for multi-point positioning on a scene. Background technique [0002] The scene multipoint positioning system is one of the new surveillance systems of civil aviation control, and it is the main surveillance method of the airport scene. The surface multilateration system is a surveillance source, and its output data may be connected to multiple different airspace systems such as the advanced surface guidance and control system (A-SMGCS), the air traffic control automation system (ATC), and the airport operation management system. Management, airport operation system. [0003] Since the input interfaces of various operating systems are different, such as network interfaces and serial interfaces, even if the network mode (UDP) is used for input, there is also the problem of isolation between different networks. In the sce...
