Surveillance and Broadcast Services System Deployment Status and APNT Applicability 2012 FAA APNT INDUSTRY DAY May 3, 2012

Overview of Presentation

• Overview of APNT candidate systems

• SBS System Deployment Status

• WAM Overlay on SBS System > Colorado Phase II Status > WAM coverage from existing radio stations

• Concluding remarks

APNT Candidate Solutions Overview

• Three approaches for provisioning APNT services are being evaluated. These are > DME-DME with INS > WAM with uplink data link > Pseudolite

• The APNT system will likely be a hybrid system, carefully chosen to maximize existing investments > The SBS system is an existing investment that should be leveraged when

making APNT decisions > The system currently provides ADS-B, ADS-R, TIS-B and FIS-B services

- A fifth service, WAM, is currently being certified in Colorado > The SBS System coverage requirements will result in a nationwide network of

radio stations. We currently estimate that the end state system will be comprised of approximately 700 radio stations - The coverage provided by these radio stations can be leveraged, today, to provide

WAM services at en route altitudes

Colorado WAM Status

• All physical infrastructure has been developed and deployed for the WAM key site > WAM Key site is Montrose CO > Design calls for a number of radio stations (built) and centralized

processing in our Redwood City, CA control station (built) • WAM testing is ongoing

> First article testing has completed with all requirements passed > System acceptance testing has completed, with some minor discrepancies

to be resolved > Operational test to be scheduled by the FAA (likely in June)

• Expect an Initial Operations Capability decision in August, In Service Decision by December

Concluding Remarks

• SBS System deployment is well underway, with over 420 radio stations built to date (33 in Alaska, 391 CONUS)

• A fifth service, WAM, is nearing qualification completion

• The SBS system will provide substantial WAM coverage with centralized WAM processing

• This infrastructure investment should be leveraged for APNT
