[745] Automatic Dependent Surveillance - Broadcast (ADS-B)
Detail Data
ID: 745
Acronym: ADS-B
Name: Automatic Dependent Surveillance - Broadcast
Type: Service
Description: ADS-B will be implemented by the Surveillance and Broadcast Services (SBS) Program to provide two services: (1) "Critical Services" consisting of ADS-B and ADS-Rebroadcast, and (2) "Essential Services" consisting of Traffic Information Service Broadcast (TIS-B) and Flight Information Service Broadcast (FIS-B).  Nine ADS-B enabled applications will be developed and assessed: (1) ATC Surveillance, (2) Enhanced Visual Acquisition, (3) Enhanced Visual Approach, (4) Final Approach and Runway Occupancy Awareness, (5) Airport Surface Situational Awareness, (6) Conflict Detection for flight and Air Traffic Management (ATM) operations, (7) CDTI Assisted Visual Separation (CAVS), (8) Interval Management (e.g., merging and spacing) and (9) Weather and NAS Status Situational Awareness. SBS will provide data to FAA defined Service Delivery Points (SDP) as the demarcation points between SBS-provided services and ground-based user systems.

The SBS applications span all national airspace domains (Oceanic, En Route, Terminal and Surface) and require tightly coupled coordination with the Terminal and En Route Service Units. Interfaces will be integrated to all major automation platforms that serve the NAS - En Route Automation Modernization (ERAM), HOST Computer System (HCS), Microprocessor En Route Automated Radar Tracking System (MEARTS), Standard Terminal Automation Replacement System (STARS), Common Automated Radar Terminal System (CARTS) and Advanced Technologies and Oceanic Procedures (ATOP).

SBS will be implemented in two segments. The SBS Program will develop connectivity and validate ADS-B suitability for ATC services through integration to the five primary automation platforms and establish an In-Service Decision (ISD) on ADS-B, ADS-R,TIS-B and FIS-B in Segment 1 by 2010. Additional capabilities (e.g., integration with ATOP) will be addressed as system enhancements in Segment 2 by 2013.

The SBS vendor will install and own about 340 SBS ground stations in three regions of the U.S. by 2010 with an option to install over 400 more by 2013. The SBS vendor will provide SBS capability to the FAA under a fee-for-services arrangement.

SBS - Segment 1:
The SBS Program has achieved Segment 1 milestones up to contract award, including the initation of deployment of essential services (TIS-B and FIS-B) NAS-wide, and other ADS-B related programs activities. An ADS-B  Notice of Proposed Rulemaking (NPRM) was also published. Key remaining Segment 1 implementation milestones are:
1. Complete deployment and certification of equipment to support service delivery in selected locations
2. Certify ADS-B as an approved surveillance source to support existing separation standards on five FAA automation platforms - ERAM, HOST, MEARTS, STARS, and CARTS
3. Publish ADS-B  Final Rule
4. Confirm minimum avionics performance to ensure future utility.
5. Define additional aircraft to aircraft requirements
6. Achieve early benefits in non-radar airspace

ADS-B critical services (ADS-B downlink to ATC for separation) will be implemented at four key sites (service volumes): the Gulf of Mexico; Louisville, KY - Terminal Radar Approach Control (TRACON) and UPS GOC; Philadelphia, PA - TRACON; and Alaska Anchorage Center and Juneau Air Traffic Control Tower.

SBS - Segment 2:
SBS capabilities will be activated in the remaining NAS service volumes with plans to complete NAS-wide deployment of ADS-B by 2013. The ADS-B  Final Rule for broadcast will be published during the end of Segment 1 and beginning of Segment 2, providing an equipment baseline to continue user equipage and application development and deployment.

Milestones beyond 2013 are:
1. Continue aircraft to aircraft application requirements definition and deployment with a goal of achieving avionics equipage of 100 by FY 2020.
2. Complete removal of targeted legacy surveillance systems, per the ADS-B Backup Strategy, between FY 2020 (Source: Roadmap Domain Lead)
