摘　　要：近年来,国外的机载互联网技术越发成熟,早于2009年就开始起步,并于2013年开始递增式发展。美国航空和美联航机队的空中上网设备覆盖率达93%,反观国内空地互联网的普及率仅为5.5%。国内基于卫星互联网的机载上网服务及机载软件技术发展刻不容缓。文章调研了国内外卫星互联网的发展情况,主要比对机载娱乐通信IFEC系统,提出国内发展IFEC系统及该系统流畅性的重要意义,重点讨论机上内容的更新与迭代方式,设计并实现基于卫星互联网的机载内容自动更新系统。在设计过程中,主要依赖于飞机在空中3000米以上接入卫星网来实现在更新过程中用户使用的稳定性。从更新内容到更新方式两方面出发,把该系统分为地面控制端与机上控制端两部分,以及使用消息通道作为收发指令,实现机载内容的可靠更新。In recent years,the airborne Internet technology in foreign countries has become more and more mature,which began in 2009 and began to develop incrementally in 2013.The coverage rate of in-flight Internet equipment of American Airlines and United Airlines reached 93%.On the other hand,the penetration rate of domestic open space Internet is only 5.5%.The development of airborne Internet service and airborne software technology based on Satellite Internet in China brooks no delay.The main contents of this paper are as follows:Investigate the development of Satellite Internet at home and abroad,mainly compare the airborne entertainment communication IFEC system.It also points out the importance of developing IFEC system in China and the smoothness of the system.The update and iteration of on-board content are mainly discussed.Design and implement an airborne content automatic updating system based on Satellite Internet.In the design process,two parts are considered:the update of the aircraft on the ground and the update of the aircraft accessing the satellite network more than 3000 meters in the air.The stability of user use in the update process is considered.From the two aspects of update content and update mode,the system is divided into two parts:the ground control terminal and the onboard control terminal,and the message channel is used as the sending and receiving instruction to realize the reliable update of airborne content.
