  1. Small Aircraft Transportation System (SATS) ….Airplanes …As a Network…. The Airborne Internet Collaboration and Working Group at the Digital Aviation Systems Conference October 16, 2003 by Ralph Yost Innovations Research Division, ACB-100 William J. Hughes Technical Center

  2. The Small Aircraft Transportation System is a safe travel alternative, freeing people and products from transportation system delays,by creating access to more communities in less time. A Key to the “Transportation System after Next”

  3. Airborne Internet is an “Enabling Technology” for SATS, …a disruptive innovation for aviation… Analyses Downselect …but not necessarily tied to SATS. Laboratory Evaluations Downselect Simulation Experiments Technology Integration And Flight Experiments Airborne Enabling Technologies Downselect Flight Experiments Downselect Integrated Flight Demonstrations

  4. AIRBORNE INTERNET What IS this thing? (and what it is NOT) A private, secure and reliable peer-to-peer aircraft communications network that uses the same technologies as the commercial Internet. A general purpose, multi-application data channel for transportation * It is NOT the World Wide Web ! *

  5. What Is a Disruptive Innovation?

  6. The Cycle of Revolutionary Advances in (Disruptive) Technology R&T Development & Evaluation Phase Initial Acceptance Phase Transition development International endorsement Deployment Phase System Maturity Phase Idea is proposed, briefed, funding sought SystemDeployment Maturation System Development Airborne Internet Evolution Airborne Internet Development Proof of Concept Revolution 2002 2007 2012 2017 2022 20XX Airborne Internet has potential for significant impact in aviation

  7. Disruptive Innovations in Higher Speed, Longer Daily Range Travel and Information Connectivity Relative Market Growth GAP Engines VDL, ACR GPS Small Aircraft Transportation System 33 years Jet Transports Jetliners Displace Props First VORs DC-3 Assembly Line Propliners Displace Cars Model T Cars Displace Trains 1900 1910 1920 1930 1940 1950 1960 1970 1980 1990 2000 2010 2020 2030 Airborne Internet Information Connectivity is now being applied to personal mobility

  8. Traditional Systems Deployment Consider the traditional method of deploying new systems in civil aviation… The FAA is currently beginning to provide ATC information (TIS) to GA aircraft…….it has long recognized the desire of GA to obtain real time weather information (FIS).

  9. FAA’s Planned East Coast Broadcast Services Functional Architecture MFD UAT ADS-B ADS-B TIS-B FIS-B Airborne Configuration FIS Sources UAT Tx/Rx Ground Stations FIS FIS-B Ground Broadcast Server(s) Surveillance Processing Surveillance Systems ADS-B TIS-B Target Reports ADS-B Flight Following (Limited) Sensor Sites Target Reports Control Facility (WJHTC)

  10. FAA’s Planned East Coast Broadcast Services Functional Architecture • Great initial start that recognizes that GA aircraft need traffic information also • An entirely new network of ground transmitters must be installed • This new network only applies to GA • Yet ANOTHER radio must be installed in the aircraft ! • Applies only to low altitude flight <18,000’) • What about high altitude GA aircraft?

  11. Radio Frequency (RF) Coverage 25 Ground Stations Mean Sea Level Above Ground Level

  12. UAT Deployment vs. A.I. If Airborne Internet were deployed today, there would be no need for • The new network of ground based transmitters • The additional radio in the aircraft • The recurring costs associated with the ground stations and additional avionics • The dual system for GA (UAT) and commercial (1090Mhz squitter)

  13. Result of the Current (and traditional) Method of Deploying New Systems in Aviation (The FAA Tech Center’s BE200N35 R&D Aircraft Flight Deck)

  14. The Cockpit of the future…….? NASA SATS aircraft interior conceptual drawing ….digital systems will require DIGITAL CONNECTIVITY !

  16. Aviation Information of the Future

  17. Aviation Information of the Future • …..and eventually, pilots will be able to extract data using VOICE….on the Airborne Internet. Voice Extensible Markup Language (VoiceXML) allows a user to interact with the Internet through voice-recognition technology by using a voice browser W3C (the WWW Consortium) is currently writing version 2.0 of VoiceXML standard Editors are from PipeBeach, Nuance Communications, Speechworks International, Lucent, Motorola, IBM, and Tellme Networks

  18. B B Technology: Goal • Analog technology foundation • Dual function transponder • Line of sight • Provide aircraft altitude, range, ID code • Extensive processing can provide flight trend prediction • Flight coverage is geographic dependant • Low altitude gaps • Many GA airports not covered A.I. Application Example: Surveillance Radar Augmentation A/C tracking depends on secondary surveillance radar Transponders in A/C reply to ground interrogations from surveillance radars. ATC has positive knowledge of A/C position, altitude, etc. Outside of radar coverage ATC has no positive knowledge of A/C position, altitude, etc. • Use checkpoint reporting Current System: Limitations: Radar dependant airspace. Radars are installed as airspace traffic density increases (e.g. NE U.S.)

  19. Comparison - Radar & ADS-B

  30. AIRBORNE INTERNETNASA TGIR Award Winner Winner of NASA’s Turning Goals Into Reality Award for Mobility Award presented June 11, 2003

  31. AIRBORNE INTERNET Next Steps….How to Advance? • Provided demonstrations and briefings over a 6 months period to key decision makers in FAA, NASA, DoD, industry Requested FAA Tech Center funding for R&D Sought sponsorship in FAA HQ Sought sponsorship in NASA Lightly explored DoD sponsorship • Conducted a spectrum study to look for ideal home for A.I. • Purchased A.I. demo equipment for NASA at LARC

  32. AIRBORNE INTERNET Move the effort OUTSIDE of the FAA Create an external “pull” on the FAA Recognize that industry has a more powerful voice in influencing the FAA than its own technical experts do ! Explore partnerships!

  33. AIRBORNE INTERNET Create the Demand and Sponsorship Create an Industry sponsored consortium to advance A.I. • Attracts industry funding • Gov’t can contribute

  34. AIRBORNE INTERNETThe Airborne Internet Working Group The AIWG is a public-private collaboration group formed to further the vision of creating and implementing an Airborne Internet data channel for aviation Five meetings held thus far Includes Microsoft, Boeing-ATM, Aerosat, NASA, FAA, ARINC, SITA, VA SATSLAB, Ohio Univ., and others Positive progress towards the creation of the Airborne Internet Consortium (public-private partnership) Developed an A.I. Work Plan ($30 Million)

  35. Airborne InternetFollow on Research • Establish Airborne Internet lab/operational system at FAA William J Hughes Tech Center • Use VDL Mode-3 NEXCOM radios • Use VDL Mode-2 radios (??? CPDLC 1A is canceled) • Explore mixed mode operations (VDL-2,3,4 mixed) • Use hybrid radio (VHF/SAT) • Explore 5Ghz C-Band solution (MLS band) • Establish A.I. Architecture as independent of radio used

  36. Airborne InternetMore Follow on Research • Add VoiceXML capability • Continue to progress with the Airborne Internet Working Group • Testing of VHF channels (possible combining of 25Khz channels to improve VDL3 bandwidth and data throughput) • Explore the possibility of using UHF spectrum (ie military partnership!) • Explore a multi-band approach • Ensure that all layers of the communications stack are thoroughly studied

  37. Potential Benefits • Using NEXCOM, A.I. data channel could be in all aircraft (i.e. no additional equipment required) • Provide ATC coverage to aircraft using non-radar covered airports (No ground equipment required at airport) • Surveillance augmentation includes Gulf of Mexico and Oceanic • ATC Flight following to more GA aircraft • Data transfer and applications available to commercial and GA • Spectrum/cost efficient: many functions over a single frequency (Minimizes the number of systems in aircraft and on the ground) • Digitized Voice/Voice over IP

  38. AIRBORNE INTERNET Summary A.I. is a general purpose, multi-application data channel for transportation A.I. is a private, secure and reliable peer-to-peer aircraft communications network that uses the same technologies as the commercial Internet A.I. can increase aviation safety by providing ATC services to aircraft not otherwise able to receive them A.I. can increase aviation safety by providing ATC services to aircraft over Gulf of Mex. and Oceanic A.I. can reduce systems costs for user and provider (and create revenue) by running multiple applications over a common data channel

  39. OK……....So Let’s GO!
