民航空管系统中气象观测、自动转报、飞行管制等工作均需以准确的时间服务为参照条件,为保证各系统时间的一致性和准确性,设备运维人员需要定期对各系统进行校时维护.目前,空管系统普遍采用北斗卫星定位或全球卫星定位(GPS)时间服务器授时,其高效、便捷、稳定等特点,深受业界青睐,对空管设备运维保障工作具有重要意义.该文从授时方法及故障处理方面对卫星同步时钟授时系统进行分析与讨论.
Application of Satellite Synchronous Clock in Civil Aviation Air Traffic Control System and Analysis of Typical Fault Cases
Meteorological observation,automatic reporting,and flight control in civil aviation air traffic control systems all require accurate time services as reference conditions.In order to ensure the consistency and accuracy of the time of each system,equipment maintenance personnel need to regularly calibrate and maintain the time of each system.At present,the air traffic control system generally uses Beidou satellite positioning or global satellite positioning(GPS)time server timing,which is highly favored by the industry due to its high efficiency,convenience,and stability,and is of great significance for the operation and maintenance of air traffic control equipment.This article analyzes and discusses the satellite synchronous clock timing system from the perspectives of timing methods and fault handling.
