Description / Abstract: Contains operational guidelines and recommendations for the implementation and utilization of Aeronautical Mobile Satellite (Route) Services, voice communication functions in the near-term (circa 1993-1996) air traffic environment. It presents a system-level view of how satellite voice services can be implemented and used in the Air Traffic Services (ATS) and Aeronautical Operational Control (AOC) environments inclusive of aircraft installation requirements, ground infrastructure requirements, and available AMS(R)S services. This document defines the functions and performance needed to facilitate the development, implementation, certification, and operational use of satellite voice in an environment where satellite voice communication is not yet a required capability for air navigation. It uses as its basis the existing standards for satellite avionics and ground equipment. It should be useful to designers, manufacturers, installers, and operators of equipment used in AMSS voice service.
