  2. Contents • CASCADE Validation approach • Priorities for 2005 • Trial sites and ground station deployment • Results from validation of applications • Results from validation of infrastructure • Future highlights • Conclusions

  3. Validation Approach • Trials and Simulations for the applications and infrastructure • With involvement of controllers and pilots where possible • Using state-of-the-art infrastructure components and validation tools (such as the ADS-B Validation Testbed at EEC and locally) • Trials Characteristics: • In an environment where the need exists • Integrated in operational systems (air and ground) • CRISTAL projects: Partnerships with the local stakeholders (common contribution of resources) to perform validation on site

  4. Validation main priorities in 2005 • ADS-B NRA • Ops usability in continental airspace (Kiruna Sweden) • Technical feasibility in non-continental airspace (Ireland) • ADS-B RAD • Ops applicability and technical feasibility (London TMA) • S&M • Ops usability and Benefits (Paris, Frankfurt) • SUR Infrastructure • Fleet monitoring report (various sites) • 1090 ES datalink capacity assessment (update) • Intermediate results of ADS-B/radar etc. data fusion (ARTAS evaluation)

  6. ADS-B NRA in continental airspace (Kiruna, Innsbruck) • ADS-B foreseen for operational use in Kiruna (Sweden) from late 2006 onwards • Main issue is the mixed traffic operations • Phase 1 implementation: ATS based on ADS-B is ceased when at least one non-equipped target enters the TMA • Phase 2 implementation: Traffic segregation procedures, to allow “clean” airspace parts or routes • To be simulated in CRISTAL Sweden (by end 2005 with LFV and in 2006 at EEC) • Offers the potential for benefits/incentives (e.g. direct routes) to the ADS-B equipped a/c • Implementation horizon is 2007-08 • ADS-B NRA also being tested in Innsbruck (in combination with MLAT) • Use of ADS-B with MLAT is gaining increasing demand by the stakeholders

  7. ADS-B NRA in non-continental airspace (Ireland) • ADS-B for long-range coverage in Shannon FIR (Atlantic ocean) • Radar coverage limitations in around 250 nm • Being investigated by CRISTAL Ireland (with Irish Aviation Authority and Raytheon) • 1090 Ground station installed in Mt. Gabriel • Demonstration earlier this year with satisfactory results • ADS-B data collection ongoing • To be followed by data fusion and evaluation by local controllers

  8. ADS-B RAD in UK (SE England & Scotland) • CRISTAL UK Phase I Study performed by NATS and Helios TL • main focus on SE England Terminal Control area • gap filer for radar in Scotland • Compared current radar system (2004) with ADS-B plus radar mosaic system for 2015 • performance, coverage and safety hazards • Appropriately placed ADS-B stations could provide adequate coverage of all SE England terminal airspace • Increased traffic levels could be “traded-off” with increased accuracy of ADS-B. • ADS-B provides a lower collision risk • Current 1090ES ADS-B does not furnish all the data required for enhanced SUR • notably selected altitude (available under DO-260A) • ADS-B presents more hazards than radar but is not unsafe • adequate mitigations were identified • ADS-B can match radar performance in all Scottish areas considered

  9. ATSAW for GA in Ostgota (Sweden) • ATSAW use by GA being investigated in the context of CRISTAL Sweden (with LFV) • Co-operation with the EGOA project of LFV • Trial planned for the 26th of October in Ostgota Terminal area (S.W. of Stockholm) • 10 aircraft planned to participate • Operational need driven by the SSR gaps at low altitude, mixed traffic etc. • Safety is the main objective

  10. S&M simulations Paris-like and Frankfurt • Two S&M Real Time Simulations performed • For Paris-like airspace (with EEC/Cospace) • For Frankfurt airspace (with DFS) • Potential benefits of S&M (in co-existence with AMAN) confirmed in the Cospace simulation • S&M is considered as the most promising ADS-B application of the ones currently validated • S&M potentially beneficial in Frankfurt, but: • Improved airspace – longer sectors, de-conflicted airways (no crossing traffic or solved procedurally) • Improved S&M procedures are needed • No plan at this stage for such changes in Frankfurt • Increasing realism is the objective of the future simulations

  11. Airborne Monitoring • Monitoring of 1090 ES equipage ongoing at various sites (using the BDAMS tool) • 1090ES equipage is high and increasing almost linearly by 2% per month • In August 2005: Mode S Elementary 74.3%, Enh. Surv. 66.2%, 1090Ext. Squitter 35.5% • Equipage level depends on the set of radars used • Non core area radars provide somewhat lower equipage percentages • Transponders don’t declare ES capability consistently • A large percentage of 1090ES capable transponders do not provide valid NUC values (Figure of merit) • Need to standardise derivation of NUC values in the transponder

  12. Data fusion (ARTAS in various sites) • Surveillance data fusion functionality has been developed for operational use • ARTAS V7A1: processing classical radars, Mode S and ADS-B • On the basis of the ARTAS version which is already operational in 10 sites and planned to be operational in 15 more sites of Europe • FAT completed in mid-05 • The current ARTAS Users will receive the s/w upgrade in Dec 2005 • Several countries (within CRISTAL projects) will now evaluate the ADS-B functionality of ARTAS • Austria, Greece, Ireland, Portugal, Spain, Sweden, UK etc. • In addition to EEC

  13. Towards ADS-B certification (Toulouse) • ADS-B data collection and analysis from AIRBUS test and ferry flights as well as from opportunity traffic around Toulouse airport • Performed by CRISTAL Toulouse (with AIRBUS, DSNA, Thales ATM, Alticode) • Comparison of airborne and ground ADS-B data as well as radar data • Using representative transponder installations (Rockwell, Honeywell and ACSS) and a 1090 GS (Thales ATM) • Deliverables include the ADS-B Certification roadmap (12/05) and ADS-B separation minima study (03/06)

  14. 1090 MHz Datalink Capacity Study • Capacity for Core Europe was studied for the last time in 2001 • TLAT (2000), EUROCONTROL/FAA (2001) • Suggested that congestion was likely in Core Europe towards 2015 • Especially for airborne 1090ES reception • Since then, several parameters have evolved • Traffic forecasts (reduction of 25% in air traffic predictions for 2015) • Mode S and 1090 ES deployment (fruit model has been validated) • New decoding techniques are available (evaluation ongoing) • A new study is currently performed with Helios TL, Raytheon SL, and NATS • Including scenario development, receiver and fruit modeling and performance simulations for the period to 2015 • Results (by Oct 2005) are expected to indicate a significant increase in the lifetime of 1090ES

  15. Upcoming highlights • ADS-B for Ground Surveillance in South Europe • CRISTAL Mediterranean (Italy, France, Malta, Greece, Cyprus) • CRISTAL Iberia (Spain, Portugal) • Pre-operational trials of ADS-B out in a hub (or hubs) • Certified equipment onboard • Participation of at least one airline • CRISTAL Toulouse Phase 2 (tbd) • ADS-B RAD in S.E. England (CRISTAL UK Phase 2 ) • ATSAW simulations/trials • Evaluation of TIS-B over 1090 datalink • CRISTAL Germany • Interest to support ATSAW applications with TIS-B • S&M Fast-Time-Simulations for the Paris airspace • CRISTAL Paris

  16. Conclusions • CASCADE continues its intensive efforts towards validation of ADS-B applications and infrastructure • Based on the local operational needs • In partnership with its stakeholders at various ECAC sites • Using the current state-of-the-art infrastructure components and validation tools (at EEC or locally) • Pre-operational trials for some of the Ground SUR applications (e.g. NRA, RAD) expected from 2006-07 onwards • Operational use of GSA could be expected to start from 2008-09 onwards, depending on the local plans • Emphasis will shift from GSA to ATSAW applications and infrastructure
