Form 9.B Project Summary

Chron: 972269

Proposal Number: 05.01-7079

Project Title: Shared - Bandwidth Broadcast FIS System

Technical Abstract (Limit 200 words)

NavRadio proposes to develop a system which allows a single aviation VHF frequency to be shared by an existing audio broadcast signal and a VDL Mode 2 digital datalink broadcast system. This will allow addition of datalink broadcast capability to numerous existing facilities, without using any additional frequency spectrum or bandwidth, and without the need for coordination or assignment of new frequencies in potential conflict with existing services. The end result is enhanced effectiveness of the existing facility by adding digital dissemination, and enhanced VHF spectrum capacity by accomplishing FIS data broadcast without use of additional spectrum, thus reserving scarce spectrum for other interactive analog and digital services. The system is designed to be easily retrofitted to existing certificated facilities without change to any hardware or software, except for replacement of the in-lace VHF transmitter with a new one. The proposed product also includes all necessary data interfaces and processing to connect a variety of Flight nformation Services (FIS) data sources to the Shared Bandwidth transmitter, and manage the dual flow of voice and data automatically.

Potential Commercial Applications (Limit 200 words)

Upgrade of or initial installation with audio broadcast NAVAIDs such as automated weather systems (AWOS, ASOS, automated unicoms), voice advisory systems (ATIS), Remote Communication Outlets, or Automated Voice Altimeters (AVA) for addition of digital data broadcast. Potential customers include federal, state and local governments, airport authorities and operators, air carriers, and government and industry providers of Flight Information Services (FIS) worldwide. In addition, near-term deployment of a digital FIS broadcast capability, using the international VDL Mode 2 open standard, will fuel econdary commercial opportunities for a variety of end-user products such as airborne displays, receivers, and information services. Such a near-term deployment is facilitated by the lack of need for additional VHF frequency spectrum.
