中国民航VHF地空数据通信网二期工程已经通过验收,它意味着继前期兴建的25座远端地面站之后,又有55座远端地面站投入使用,基本覆盖了我国6600米以上的高空航线。VHF地空数据通信网是中国民航为实现新的CNS/ATM系统(通信/导航/监视和空中交通管理)过渡而建设的第一个基础设施工程,为我国航空运输的现代化管理奠定了坚实的基础。一、VHF的优越性 VHF数据链是利用先期建好的地面站与飞机上的专用机载设备进行联系,以数字通信方式传递各种信息的一种方法,与传统通信手段相比有着突出的优越性。 1.数据链通信效率极高由于是数据通信,信息传递的速
China Civil Aviation VHF air-ground data communications network has passed the second phase of acceptance, which means that after the previous construction of 25 remote ground stations, and 55 remote ground stations put into use, covering almost 6600 meters above sea level in China route. VHF Ground Data Communication Network is the first infrastructure project underpinned by Civil Aviation of China for its transition to a new CNS / ATM system (communications / navigation / surveillance and air traffic management), laying a solid foundation for the modernization of China’s air transport basis. First, the superiority of VHF VHF data link is the use of pre-built ground stations and aircraft dedicated onboard equipment to contact, a variety of ways to transmit digital communications a method, compared with the traditional means of communication has a prominent Superiority. 1. Data link communication efficiency is high because it is data communications, the speed of information transmission
