This document sets forth the desired characteristics of the Iridium Low-Earth Orbiting (LEO) Aviation Satellite Communication (Satcom) System avionics intended for installation in all types of aircraft including commercial transport, business, and general aviation aircraft. This document provides a description of the system components, aircraft interfaces, and satellite communication functions. It also describes the desired system performance and operational capability of the equipment. This characteristic specifies equipment using the next generation of Iridium satellites (referred to as Iridium NEXT) operating in L band with launch starting in 2017 and completed network by 2018. The services used on the NEXT network are referred to as Iridium CertusSM. Based on maximum baud rates, the following Certus Service Classes are defined: Certus 100, 200, 350 and 700. With backward compatibility, the Iridium NEXT/Certus satellite network replaces the Iridium legacy satellite network known as Block 1.
