Satellite Low Rate Voice Demonstration Test Plan

Abstract

This test plan describes the design of the demonstration of a low data rate voice Codec communications link via satellite. The demonstration will include the use of 4.8 kbps voice Codec equipment interfaced with a mobile satellite (MSAT) communications terminal installed in the Federal Aviation Administration's (FAA's) B- 727 (N-40) aircraft and similar equipment at the COMSAT ground earth station in Southbury, Connecticut. This configuration, used in conjunction with INMARSAT satellite capability, completes an aircraft-to- satellite-to-ground facility circuit that provides a communications quality voice link between the pilot and the ground. In addition to a demonstration, techniques will be developed for evaluating voice Codecs for air traffic control (ATC) applications. Controllers from the FAA will be used in the evaluation. A Codec Test Bed Facility will be developed to conduct stress testing in a laboratory controlled environment. This project will allow critical evaluation of digital voice satellite communications technology in a simulated ATC environment.
