The Ku-Band and Ka-Band Satcom Subcommittee is developing standards for broadband satellite system hardware and aircraft installation provisions. The objective is to define Ku-Band and Ka-Band satellite communication (satcom) equipment, installation, and necessary interfaces to aircraft systems. This activity is working closely with AGCS, NIS, and CSS. The Ku-Band system is being defined in ARINC Project Paper 791.
Ku-Band and Ka-Band satcom equipment standards provide airlines with freedom of choice of their internet gateway service provider and the associated equipment, which are intended for use by airline passengers and crew. Passenger services are provided in coordination with evolving cabin system standards and In-Flight Entertainment (IFE) standards.
Ku-Band and Ka-Band satcom services yield a wide variety of service offerings with dedicated equipment that would otherwise require custom installation. To enable the wide-spread use of this equipment, standards have been developed for Ku-band and Ka-Band satcom equipment hardware and electrical installation interfaces. The following standards define current technology systems:
Ku-band and Ka-Band satellite equipment delivers internet connectivity services to airline passengers and crew, including internet, telephony, television, and so forth. Aircraft data may be collected and sent to the airline base. Standardization has simplified the Ku-band and Ka-Band satcom system definition and lowered the cost of installation of this equipment.
These benefits have been seen on both new aircraft and in many retrofit aircraft programs.
Future Work Program:
Supplements to ARINC 791, Part 1 and ARINC 791, Part 2 to incorporate items identified in service implementation of ARINC 791 by the suppliers, service providers, airlines, and airframe manufacturers.
ARINC Project Paper 792 to:(1) Define emerging Ku-band and Ka-band Satcom components, including new antenna technologies, smaller/simpler components and installation methods; (2) Document the potential advantages and trade-offs associated with those components; and (3) Provide guidance on how to adapt ARINC 791 provisions to install them.
