Airborne Architecture V1 Airborne Architecture V1 Presentation Transcript

  • April 2006 Products and Engineering Services Project Management Enterprises, Inc. (PMEI) 7900 Wisconsin Avenue Bethesda, Maryland 20814 Tel: +1-301-652-5306 Fax: +1-301-469-9001 Contact: Prasad Nair (pn@pmei.com) (Information herein presented are confidential and proprietary to PMEI and may be subject to disclosure and use restrictions) 1 pn@pmei.com
  • Radio product family – v4.0 April 2006 (Information herein presented are confidential and proprietary to PMEI and may be subject to disclosure and use restrictions) 2 pn@pmei.com
  • EFR 400-xx series radio family – v4.0 April 2006 Air host Interface (ASI) tablet Airborne Network VDL Radio Physical size: 11.6(w) x 1.6(h) x 9.8(l) in. Physical Size: 6.11(w) x 2.02(h) x 8.27(l) inches Weight: 5.5 lbs Weight:2.987 lbs (1.355 kg) (Information herein presented are confidential and proprietary to PMEI and may be subject to disclosure and use restrictions) 3 pn@pmei.com
  • Hardware connectivity diagram April 2006 (Information herein presented are confidential and proprietary to PMEI and may be subject to disclosure and use restrictions) 4 pn@pmei.com
  • Applications supported April 2006 Autonomous peer-to-peer position location and network discovery  Low latency direct peer-to-peer messaging (automated chat)  Assured uplink broadcast services (multiple applications)  Surface movement monitoring (local and remote) with integrated  voice and text-to-voice advisory services COTS internet connectivity to ATC, AOC and APC networks (with  firewall and encryption as required) IP ground based network management for DNS and aircraft  domain address resolution Airborne Relayed Communications Service (ARCS) provides  over-the-horizon and Beyond Line of Sight (BLoS) connection management to any discovered peer or ground center APC and AOC support via out-of-band signaling  Back-up surveillance with dynamically modifiable report rate  Security and authentication services  (Information herein presented are confidential and proprietary to PMEI and may be subject to disclosure and use restrictions) 5 pn@pmei.com
  • Multi protocol radio communications April 2006 Supports COTS TCP/IP communication  Built-in:   ICAO complaint variable rate ADS-B built-in  GPS engine (not needed for AT)  TDMA RF network synchronization access  Station Identification Reports (SIRs) for net and IP handling Standard DSB/AM voice operations  Optioned multi-channel receive with real-time  dynamically assignable transmitter Ethernet and serial line connectivity to airhost/  shipboard systems (Information herein presented are confidential and proprietary to PMEI and may be subject to disclosure and use restrictions) 6 pn@pmei.com
  • Key technical features - I April 2006 Multi- channel, multi-receiver product line  - multiple receivers operate on independent channels to receive products and services simultaneously - Frequency agile transmitter services all off-board transmit requirements - Shared antenna with bus interconnect permits diversity radio operations (transmit and receive) Station Identification Report (SIR) [ADS-B like/ can be a back-up]  - lat, long, baro-alt, geo-alt, true_track, category, call_ sign, altitude_rate. (Variable rate transfer reports permit dynamic rate changes to accommodate specific airspace needs) - ipv4 address (autoconfig in v6) / hopsToGo Assured Broadcast Product Distribution (Datafeed)  - autosegmentation and reassembly of large products - ack (and selective reject) of fragments to optimize delivery schedule - use of target location to optimize delivery schedule (e.g., aircraft on final MUST have l latest arriving-atis) - use of aircraft existence to know who has received what and who needs what to dynamically manage broadcast product mix e-Mail  - delivery to arbitrary ground host - delivery of air-air occurs directly if in LoS of each other (else air-ground-air) - delivery from arbitrary ground host goes direct to next hop ground station (Information herein presented are confidential and proprietary to PMEI and may be subject to disclosure and use restrictions) 7 pn@pmei.com
  • Key technical features - II April 2006 Instant messaging (XMPP)  - delivery via non-jabber gateways to arbitrary client - delivery of air-air occurs directly if in LoS of each other else via ground-proxy - delivery to and from arbitrary jabber ground server Web browsing  - proxy in air/ground for compression and to push DNS lookups from transiting the RF Cloudburst  - VoIP and other isochronous services Arbitrary IP  - routes arbitrary IP packets either directly air-air or air-ground if no air-air path - supports full 16 levels of priority using the ToS field as the priority indicator - handles packets up to 1500 bytes (standard Ethernet frame) and is a valid IPv6 subnetwork (IPv6 requires a minimum MTU of 1280 bytes) (Information herein presented are confidential and proprietary to PMEI and may be subject to disclosure and use restrictions) 8 pn@pmei.com
  • Airborne network capability demo configuration April 2006 Satellite Datalink Service Provider (Irridium or similar) Satcom interconnect to be completed Multiple routing algorithms available (est. 1 month effort) Air-to-air routing AND Min_Time_Max_Performance presently implemented Air-to-ground via satellite gateway (single assured route) (gateway on-board for test/demo) Air-to-air routing and Air-to-ground comm. Remote Ground Station Internet Ground Station Surface Networks (Information herein presented are confidential and proprietary to PMEI and may be subject to disclosure and use restrictions) 9 pn@pmei.com
  • Example NAS ARCS network lay-down for enroute and terminal operations proof-of-concept April 2006 BLoS network enabled VDL system IP information transport above MAC layer IP Packet routing with optimized hop count policy implemented for performance Route recording for loop detection and optimization Standard SMTP mail and IM services (a/g and a/a) Station ID Reports maintained for all a/c with ADS-B fall-back at Ground Control Center(s) Oceanic approach/ departure services and gulf operation monitoring (Information herein presented are confidential and proprietary to PMEI and may be subject to disclosure and use restrictions) 10 pn@pmei.com
