scope:

The document provides Minimum Aviation System Performance Standards for data communications utilizing aeronautical mobile satellite systems for the air-ground communications subnetwork in an Aeronautical Telecommunications Network (ATN) environment. The document focuses on data versus voice and covers a broad range of satellite systems to include the current and next generation satellites. The FANS 1/A data link environment is also addressed. Where systems are global in nature, the system may have international applications that are taken into consideration. Communications supporting the Air Traffic Service (ATS) and Aeronautical Operational Control (AOC) may be provided by one or more satellite systems, each of which has particular operating characteristics. This document anticipates that the system-specific attachment(s) will provide one means of assessing whether a particular AMS(R)S system is appropriate for a specific operational environment. The requirements for operational environments are consistent with DO-264.
