EMERALD WP5

The Specific case of ASAS/ADS-B


EMERALD WP5 Work

• Task WP5.1: Identification of potential ASAS applications

• Task WP5.2: Detailed feasibility assessment of selected ASAS applications

• Task WP5.3: Users’ Interview

• Task WP5.4: Assessment report and RTD plan

• Task WP5.5: Users’ feedback and final results presentation


EMERALD RTD Plan

• User Requirement or concept phase

• Feasibility phase

• Functional Requirement phase

• Prototyping Phase

• Experimentation & Validation phase

• Implementation phase


WP5 recommendations

• The proposed RTD plan be used as a guide for further

research into the ASAS domains by the RTD funding

authorities

• The RTD activities described in the RTD plan be

undertaken quickly in order to cope with the EATMS

schedule for ‘Co-operative ATM’

• Co-ordination between all organisations involved in ASAS

studies be undertaken


Project EMERTA


Objectives of Project EMERTA (1/3)

To establish the feasibility of using emerging NGSS services ‘as they are’ to meet Air Traffic Service (ATS) and Airline Operation Center (AOC) requirements. This will include the definition of a European-level NGSS demonstration/validation project.

To support a European input to international standardisation activities in such forums as ICAO and RTCA/EUROCAE, insofar as they are concerned with the technologies and concepts covered by Project EMERTA.



To provide inputs to the specification of detailed requirements for a second generation of Low/Medium Earth Orbit (LEO/MEO) satellite systems and services, for deployment beyond the year 2005.

To assess the practical feasibility of the early introduction, in the European ATM environment, of one or more selected ADS-B/ASAS application scenarios, paying particular attention to safety and transition aspects. This will be supported by an outline indication of the cost/benefit issues associated with the scenario(s).



To develop initial indications and guidelines on how to deploy ADS-B in Europe, in the context of the ASAS concept, in terms of the potential requirement for reserved airspace and how best to deal with a mixed aircraft population (where some aircraft have an ASAS capability, but others do not).


TIS-B conclusions

• TIS(-B) has a role to play in enabling the initial implementation of ASAS applications

• An ongoing role to support ASAS operations could also be identified.

• The concept of a service volume is key.• An agreed TIS(-B) concept must be defined as the

international standardisation activity continues and further requirements become available.


For EMERTA, two applications were chosen:• Enhanced Visual Acquisition (EVA) of other

traffic for see-and-avoid

• Station Keeping on Approach (SKA)

Two applications were also taken from EMERALD:• Closely Spaced Parallel Approaches (CSPA)• Longitudinal Station Keeping (LSK)

ASAS Applications


EMERTA Conclusions (1/2)• Technology is available to support basic ASAS

applications• Major gap is in the surveillance data quality• SKA has been shown to be feasible in the short-

term• TIS-B could be an enabler for early applications

and provide a consistent traffic situation picture


EMERTA Conclusions (2/2)

• Initial applications must be chosen carefully• Relevant procedures must be developed• Responsibilities must be defined• Issues of confidentiality• Technical data-link issues must be closed• Implement supporting ground systems • Address CDTI HMI issues
