Managing Ultra-Wide Band Technology Impact on Aviation: Updates and Recommendations

This seminar, presented by EUROCONTROL, addresses the impact of Ultra-Wide Band (UWB) technology on aviation. It discusses the outcomes of recent consultations and testing on UWB emissions affecting radars, radio altimeters, and MLS systems. Future steps involve testing affected services and cooperating with PULSERS for validation. Attendees aim to influence the closure process of ECC/TG3 as needed.

Presentation Transcript

  1. ICAO Seminar on Aeronautical spectrum management(Cairo, 7 – 17 June 2006)ULTRA WIDE BAND TECHNOLOGYA THREAT OR NOT TO AVIATION ?(presented by Eurocontrol)

  2. STATUS • TG 1/8 CLOSED THE UWB QUESTION IN ITU Autumn 2005 • Outcome: recommendation made however ultimate decision on UWB emission limits and regulation left with the State • TG 3 (The European technical study group), reviewed this decision and put forward proposed European limits to ECC • ECC consultation process • on general UWB applications closed on 24/12/05 • On 3.1-4.8 GHz applications closed on 29/05/06 • Aviations (EUROCONTROL + Adm.) complained for radars, radio- altimeters and MLS • Outcomes: 24/12/05 More stringent values in order to better protect primary radars

  3. ECC versus aviation limits

  4. So what is done/planned ? 1. Response to the consultation process 2. Testing of the 4 ‘threatened’ services with real UWB signal - UK Radar tests -DFS radar tests -Eurocontrol/EC PULSERS1 testing (emphasis should be on 9 GHz airport radar) 1 Pervasive Ultra Wideband Spectral Energy Radio Systems (PULSERS) – a European Industry/EC initiative

  5. UWB Allowable Field strength vs Distance UK TESTING

  6. DFS Testing • Bosch provide UWB-radar (wall probing, ..) simulators • No testing with UWB-communication with are the to-morrow mass market • Tested : PSR L an S bands, mode S, SSR • Outcomes: L band PSR is the most vulnerable to UWB-radar interference

  7. NEXT STEPS • Validation testing on the 4 affected systems, need cooperation with PULSERS • Participate in and influence ECC / TG3 closedown process as necessary
