Just before the Thanksgiving holiday, the FCC approved separate requests by ViaSat, Inc. and ARINC Incorporated to offer broadband services aboard aircraft through leased satellite transponders that will link to mobile earth stations. ViaSat’s service, dubbed “Arclight,” will utilize leased Ku-band transponders aboard the SES Americom AMC-6 satellite at 72° West Longitude. Similarly, ARINC’s “SkyLink” service will rely upon Ku-band transponder capacity provided by the Brazilian-licensed Estrela do Sul spacecraft positioned at 63° W.L. ViaSat, which is expected to offer e-mail, Internet, and corporate virtual network services to airline passengers and crew, was granted blanket authority to operate 1,000 airborne mobile earth stations that will communicate via satellite links to ground-based earth stations. Both companies are required to coordinate their operations with NASA and the National Science Foundation, which currently use some of the licensed channels for satellite communications and radio astronomy functions, respectively. The licenses are also contingent on the adoption of final FCC rules that would govern the operation of future aeronautical mobile satellite service networks. The FCC predicted that the implementation of the ViaSat and ARINC systems would boost competition within the U.S. mobile telecommunications market.
