A data recording method applied to gbas ground station

Abstract

The invention provides a data recording method applied to a GBAS ground station, comprising the following steps: S1, the configuration module of the data recording device sends configuration parameters; S2, the communication module of the data recording device establishes a connection with the GBAS ground station; S3 1. The communication module receives the time statistics data, forwards it to the state monitoring module and the time synchronization module; S4, the state monitoring module judges whether the clock source is credible, selects the time source according to the judgment result and creates a record file; S5, the communication module receives the data processor Data, write record files in real time; S6, the status monitoring module monitors the remaining space of the hard disk in real time, monitors whether the record files and folders exist, local time, and time statistics data, and skips to S5 to continue execution. The data recording method of the present invention can record the satellite data of the GBAS ground station in real time through the database or log, record alarms and user operations in real time, verify the logic processing of the GBAS ground station and perform post-processing, and the time resolution can reach millisecond level.

Description

technical field [0001] The invention belongs to the technical field of positioning, and in particular relates to a data recording method applied to a GBAS ground station. Background technique [0002] Ground-based Augmentation Systems (GBAS) is a positioning system used for aircraft precision approach guidance, which can provide accurate positioning information for aircraft during takeoff or landing phase. GBAS consists of ground station, GNSS satellite, and airborne three parts. The ground station can receive the observation information of multiple satellites to calculate the differential integrity positioning information, and broadcast it to the airborne through VHF broadcast, and the airborne can perform differential positioning calculation. And complete the approach guidance. There are many GBAS ground station system equipment, including reference receivers, antennas, processor equipment, recording equipment, power supply equipment, transmitting / receiving stations, timi...
