Presentation Transcript

  1. Future Communications Study Technology Assessment Team: Outcome of Phase II Activities Presented at ICAO ACP WGC Meeting, Brussels, Belgium September 19, 2006 Prepared by: ITT/Glen Dyer, Tricia Gilbert NASA/James Budinger

  2. Background • FCS Technology Investigation is being performed in three phases • Phase I: Technology Pre-Screening May – December 2004 • Recommended applicable satellite and terrestrial technologies (in VHF, L- and C-Band) • Phase II: Technology screening and detailed evaluation of selected technologies that scored well in the Phase 1 • This briefing presents an overview of the results from this phase • Phase III: Detailed Technology Investigations

  3. Elements of the Candidate Technology Evaluation

  4. Evaluation Methodology – Analytical Hierarchy Process (AHP)

  5. Updated Technology Inventory Note: A bold font has used to indicate the new additions to the technology inventory.

  6. Technology Screening Overview • The technology screening used key metrics to identify the most promising candidates from each technology family • The key metrics for terrestrial technologies that were selected and used are data rate and communications range • For the satellite and over-the-horizon family of technologies, the screening criteria was a gate (ability to use protected spectrum) and the technology data rate • Each technology family was assessed and plotted on a “tri color” chart, with acceptable, marginal and good regions inferred from COCR requirements • Most promising technologies from each family were selected for detailed evaluation (depending on family performance, 0, 1 or many were selected) • Next two slides provide screening results in a graphical format. The third slide provides a summary of the technology screening results.

  7. Technology Screening Summary – Terrestrial Technologies Legend Small Squares = Cellular Technologies Small Diamonds = IEEE 802 Technologies Small Triangles = Public Safety Radio Small Circle = Custom VHF Large Square = Custom Broadband Dashmark = Military

  8. Technology Screening Summary – Satellite Technologies Candidates to bring forward

  9. NASA/ITT Screened Technologies • Nine total technologies are brought forward from the Screening process • Eight are candidates that provide a general solution applicable to continental airspace (including en route, TMA and airport) • These candidates are considered further as part of a full technology investigation • Some technologies can be considered in the context of specific domains • Oceanic: Inmarsat, Custom Satellite (also counted as potential continental solutions) • Airport: IEEE 802.16e (not considered applicable as a continental solution)

  10. EUROCONTROL Screening Short List • Eurocontrol presented their current technology short list at the ICAO ACP WG-C10 meeting (March 17, 2006)

  11. Eurocontrol Common Recommendations NASA – ITT Continental • P-34 • Broadband-VHF • Wideband CDMA • Enhanced TDMA • L-band Datalink • [(x)DL3] • INMARSAT • Swift Broadband • Custom Satellite • IEEE 802.16 Continental • P-34 • Broadband-VHF • Wideband CDMA • Enhanced TDMA • L-band Datalink • [(x)DL3] • INMARSAT • Swift Broadband • Custom Satellite • IEEE 802.xx • INMARSAT • Swift Broadband • Custom Satellite • Link 16 • [(x)DL4] Oceanic Oceanic Airport Airport • ADL Comparison of Screened Technologies

  12. Initial Detailed Technology Evaluation Scores • Initial implementation of the Analytical Hierarchy Process (Detailed Evaluation Process) identifies two leading candidates, P34 and B-VHF • Additional candidates that scored well include W-CDMA, E-TDMA, and LDL • Inmarsat and emerging satellite technologies that utilize AMS(R)S spectrum score well and are recommended for remote airspace • 802.16e is recommended for use on the airport surface • Phase II in-depth technology investigations that support the Detailed Evaluations have considered P34, LDL, 802.16e and satellites; further study of the following technologies is recommended for Phase III • WCDMA • B-VHF • L-Band E-TDMA

  13. Action Request • The ACP Working Group is invited to consider the technology investigation activities described in this paper; including the methodology employed, the screened technology results and the preliminary detailed evaluation results, and to provide comments if desired
