ADS-B & TIS-B Architecture DefinitionMajor Objectives

Establish a common view of ADS-B & TIS-B functions Facilitate cross-communication between the various

corresponding European projects Provide a means towards Interoperability

Support the Validation activities Establish a logical and traceable bridge from requirements

(OSED, SPR, INTEROP) to infrastructure component specifications

Support the Validation Infrastructure Development (AVT) Support the CBA activities


OSEDs, SPR, INTEROP

Functional Architecture (FA): identification of:• functions and sub-functions (functional requirements)• high level data flows• rules for data exchange

Physical Architecture (PA): mapping of the FA requirement onto components to support infrast. dev. • Includes performance requirements/specifications• Detailed interfaces (protocol, ASTERIX, etc)

Infrastructure Component Development (AVT)

Ground Functional and PhysicalArchitecture Definition

ADS-B & TIS-B Functional Architecture: Intermediate ground FA (Functional Architecture) document

focused on TIS-B is available Work is on-going for the next version including ground

ADS-B aspects (May 2003) At a later stage, airborne aspect resulting from the study on

the airborne functional architecture will be included ADS-B & TIS-B Ground Physical Architecture (allocation

of requirements to physical components) has started

“Airborne Surveillance Functional Architecture” Study

“ASFA” Study constitutes a major ADS Programme airborne related activity centred around the Airborne SDPD function

Project teams comprise key airframers and avionics industry Project delivers :

Position Paper on ACAS-ASAS/ADS-B Relationship Functional, performance and interface requirements for an Airborne

SDPD prototype Including development recommendations derived from an analysis of existing Ground

SDPD systems

Airborne Surveillance Functional Architecture Definition Workshops facilitated exceptional platform for extensive

discussions between major industry parties

Package I CBA Activities


Package I Cost Benefit Analysis Package I CBA Study is on-going :

Review Group including NATS, IATA, LH, SAS, IAOPA, Rockwell-Collins; Airbus; CARE-ASAS

Focuses on a sub-set of applications (ground and air) with significant potential for operational benefits

The current CBA document shows : High benefits (up to 2Bn€) from :

SSR radar replacement Enhanced Visual Approaches Enhanced Sequencing and Merging;

Also, strong indications that other Package I applications will generate a very positive return on investment :

Crossing and Passing en-route; extension of S&M to the approach phase


Airborne Infrastructure Equipage Options and Scenarios

Package I Equipage Options: Option 1: “ADS-B out” Option 2a: “ADS-B in” ATSAW Option 2b: “ADS-B in” ATSAW & Spacing w/o automation Option 3: “ADS-B in” ATSAW & Spacing with automation

Option 3 upgradable to Package II at relatively low cost

Package I Equipage Scenarios : For Air Transport & Helicopters (off-shore) :

Scenario #1 applying equipage option 2a Scenario #2 applying equipage option 2b Scenario #3 applying equipage option 3

For General Aviation & Military applying equipage option 1

Package II CBA Considerations

Application Examples: Airborne separation applications (Cluster Control alone

would account for ~1B€) Airborne self-separation applications in low-density airspace

(initial high level estimates of ~1.5B€; not investigated further)

Upgradability of Airborne Architecture options, from Package I to Package II requirements is a key issue under consideration


Conclusions ADS/B and TIS-B Architecture Definition :

Establishing a logical and traceable bridge from Requirements to Infrastructure Component Specifications

Providing a means towards Interoperability Ground Functional and Physical Architecture Definition “Airborne Surveillance Functional Architecture” Study

CBA Activities : The work is on-going for review by the Review Group Package I shows potential for a positive CBA Evolution to Package II
