radomes that protect the equipment and antenna from the weather. Additional Information: http://download.harris.com/app/public_download.asp?fid=416 ADS-B (Automatic Dependent Surveillance - Broadcast) Anchorage Air Route Traffic Control was the first facility in the world to begin using Automatic Dependent Surveillance-Broadcast (ADS) for air traffic control separation services using a separation standard. It was first deployed on January 1, 2001 in that portion of western Alaska known as the Yukon-Kuskokwim Delta/Bristol Bay regions. 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/MFD 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. Implementation: 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 initiation of deployment
