Device and method for monitoring release information performance of local area augmentation system

Abstract

The invention discloses a device and a method for monitoring release information performance of a local area augmentation system, which mainly solve the problem that a release information performance monitoring system cannot acquire intermediate operation data and state data of a ground subsystem and cannot provide a fault repairing function for the ground subsystem in an operation process. In the device, a release information monitoring unit monitors performance by using the release information and navigation data output by a receiver and the transmission data of a ground network, a performance comprehensive evaluation unit makes a comprehensive judgment on the monitoring result, the ground subsystem and a control centre system provide release information contrast data through the groundnetwork, and when a reference receiver of the ground subsystem goes wrong, the ground network sends navigation observation data to the ground subsystem to repair the data of a fault receiver. The device and the method improve the precise, complete, available and continuous capability for monitoring the local area augmentation system and can be used for the release information monitoring and faultalarm of the local area augmentation system.

Description

technical field [0001] The invention belongs to the Global Navigation Satellite System (GNSS), relates to the GPS global positioning system, in particular to a device and method for monitoring and publishing information performance, which can be used for the monitoring and failure of the information released by the ground subsystem of the local area augmentation system alarm. Background technique [0002] The Global Positioning System (GPS) is a satellite-based radio navigation system. The Local Area Augmentation System (LAAS) is a Ground Based Augmentation System (GBAS) proposed by the Federal Aviation Administration (FAA). It is a differential GPS ( A type of Differential GPS (DGPS). [0003] The local area augmentation system includes satellite subsystem, ground subsystem and airborne subsystem. in: [0004] Satellite subsystem: refers to the system in which navigation satellites generate ranging signals and send them to ground subsystems and airborne subsystems.
