1 Next Generation Air/Ground Communications (NEXCOM) Briefing for Seminar on Implementation of Data Link and SATCOM Communications November 2003 Bangkok, Thailand Barbara Cassidy Federal Aviation Administration Integrated Product Team for Communications (AND-300)

2 2 Overview U.S. National Airspace System Air/Ground Communications Infrastructure Spectrum Needs NEXCOM Acquisition –What it includes –Why it is needed –Acquisition Program Elements Multimode Digital Radio Ground System Segment Avionics Development System Demonstrations Notional Transition to NEXCOM Controller-Pilot Data Link Communications Status

3 3 VHF and UHF ATC bands Approximately 11,000 VHF assignments Approximately 40,000 VHF and 10,000 UHF TX, RX & TCVRs Dedicated networks for each operational environment Limited restoral capabilities Limited remote maintenance capability National Airspace System Air/Ground Communications Infrastructure 61 AFSSs, 14 FSSs Automated Flight Service Stations, Flight Service Stations 21 ARTCCs & 3 CERAPs Air Route Traffic Control Center, Combined Center Radar Approach Control 793 RCAGs Remote Communications Air/Ground 1854 RCOs Remote Communications Outlet 175 TRACONs Terminal Radar Approach Control 1422 RTRs Remote Transmitter Receiver 346 Airport Towers 720 BUECs Back up Emergency Communications

4 4 National Airspace System Air/Ground Communications Spectrum Needs Projection Projected Low Demand 80 Circuits per year FAA Baselined Program Plans Projected Circuit Supply/ Risk Projected High Demand: 190 Circuits per year Long term historical trend Initiating study to determine means/costs of extending to 2015

5 5 What is NEXCOM? FAAs program to modernize and improve VHF air/ground communications in the National Airspace System (NAS) –Fundamental change from analog to digital technology VHF Digital Link Mode 3 (VDL-3) –Time Division Multiple Access Technology –Maintains current 25 kHz frequency separation, but –Provides 4 non-interfering channels on 1 frequency –All channels suitable for voice or data –Operates in the MHz band allocated for Air Traffic use Impacts both ground and airborne elements of the NAS

6 6 Why NEXCOM? Capacity Up to 4x Increase in Channels –Spectrum Depletion Limits NAS Expansion Efficiency Provides for Data Link –Establishes a High Integrity Data Path –Broadcast and two-way datalink to meet future Concept of Operations Safety Digital System Allows Advanced Capabilities –Eliminates Step On (anti-blocking; urgent downlink) –Provides Stuck Microphone Resolution Infrastructure Sustainment –Average age 25+ years for ground radio equipment

7 7 NEXCOM Acquisition Program Elements Demo/Stakeholder OutreachCertified Avionics Development Multimode Digital Radio (MDR) Analog & Digital modes in one radio Ground System (RPDE and FSD)* * Rapid Preliminary Development Effort and Full Scale Development Analog & digital voice and data in a single cockpit radio Show NEXCOM system architecture and commercial avionics viability MDR Radio Interface Unit Ground Network Interface

8 8 NEXCOM Multimode Digital Radio (MDR) Compatible with todays radios –Double Side Band-AM 25 kHz –8.33 kHz –VDL Mode3 –Interfaces to the future NEXCOM Ground System Replaces current NAS ITT & Motorola CM200 radios –Initial use is replacement of aging radio infrastructure Contract Awarded July 2001 to ITT – Potential procurement of 37,600 radios Initial Operation Capability mid-2004 –First use in 25 kHz analog mode (infrastructure replacement function) Transparent to users

9 9 NEXCOM Ground System Development Radio Interface Unit (RIU) –Provides remote site capability for digital communications Ground Network Interface (GNI) –Provides connectivity for voice switches Two-Phase Development –Rapid Preliminary Development Effort (RPDE) (Mar 2002-Dec 2004) ITT Corp and Harris selected as vendors in Feb 2003 –Full Scale Development Program (FSDP) (Jan 2005-Dec 2007) Only RPDE vendors compete Equipment available for deployment beginning 2008 –Initial use as infrastructure replacement of current Radio Control Equipment (RCE) VHF T/R Radio Interface Unit Ground Network Interface

10 10 NEXCOM Avionics Development Components Multimode VHF radio Radio Control Panel Communications Management Unit (optional) FAA/Manufacturer Agreements Rockwell Collins, Honeywell – air carriers (December 2001) Avidyne – general aviation (December 2001) Rockwell Collins – business jets (August 2003) Agreements include cost sharing and payable events Pre-production models used in System Demonstration II (November 2003) Certified avionics commercially available in 2005

11 11 NEXCOM Near-Term Acquisition Schedule FY 03 FY04 JanFebMar Jul AugSepOct Nov DecJan ACTIVITY AprMayJunFeb System Demo II 11/03 Ground System RPDE Contract Awards 02/03 System Requirements Review System Design Review 05/03 11/03 MDR Production Acceptance Testing Flight Coverage Testing 09/03 10/03 Avionics Draft VDL Mode 3 Characteristics submitted to AEEC 09/03 Interoperability Testing 06/03 08/03 Notice of Availability TSO 03/04 Mar Production Equipment Deployment 02/04

12 12 NEXCOM System Demonstrations Series of three demonstrations –Demo I, II at FAA Tech Center –Demo III at location to be determined Objectives –Oct 2002: VDL Mode 3 Technology viability –Nov 2003: NEXCOM Avionics & System Architecture Interoperability Vendors provide pre-production avionics –Oct 2004: Operational Suitability Support certification of commercial avionics

13 13 System Demonstration II Culmination of Interoperability Testing Activities Demonstrated the NEXCOM Avionics: –Commercial Viability –Affordability –Availability Held November 5 th and 6 th,,2003 –William J Hughes Technical Center in Atlantic City, NJ

14 14 Circa 2018 Expand Digital Voice (VDL-3) to all domains Expand Datalink Capacity in all domains and all applications (VDL-2 & VDL-3) Circa 2013 Maintain Terminal Analog Voice Implement VDL-3 Digital Voice Expand Datalink VDL-2 Applications Circa 2015 Expand Enroute Digital Voice (VDL-3) Initiate Terminal Digital Voice (VDL-3) Increase Datalink Capacity & Capability (VDL-2 & VDL-3) Analog Voice, 25 KHz Initial Datalink (VDL-2) Full Operational Evaluation & Exercise of Digital Voice and Datalink (VDL-3) Next 5 years National Airspace System Notional Transition to Digital Communications

15 15 Controller-Pilot Data Link Communications Status Controller-Pilot Data Link Communications (CPDLC) –Build-1A Project being reworked User equipage too slow Out of sync with En Route Automation Modernization (ERAM) –Air Route Traffic Control Center automation program –CPDLC deployment ahead of ERAM would have resulted in need to re-host CPDLC into ERAM –Miami operational evaluation continues In daily use by controllers and pilots Continuing role as operational test bed –Long term plans are being developed –FAA remains committed to ATC Data Communications
