1. 1 GENERAL DYNAMICS Decision Systems Michel G, Gelinas Oct. 13, 2003 ACP WGC6/WP28 General Dynamics Decision Systems and Iridium Communications The Satellite Complement To Ground Infrastructure Michel G. Gelinas Program Manager michel.gelinas@gdds.com

2. 2 GENERAL DYNAMICS Decision Systems Michel G, Gelinas Oct. 13, 2003 ACP WGC6/WP28 Ground and Space Technology Provides New Solution to Global CNS Challenge! Objective: l Provide pilots and controllers with communications, navigation, surveillance (CNS) services everywhere. Challenge: l Existing and planned ground infrastructure limited to geographically defined areas with support capabilities. Solution: l Satellite complement acts as gap filler and extends coverage where ground infrastructure is impractical or un-economical. Iridium plus ground system equals ubiquity of coverage !

3. 3 GENERAL DYNAMICS Decision Systems Michel G, Gelinas Oct. 13, 2003 ACP WGC6/WP28 The Incubation Phase - Alaska Barrow Nome Fairbanks Anchorage Bethel Juneau Ketchikan Shemya 0.2% of USA pop. 1/5 of USAPop. Density 0.24 person/sq. mile 7,000 airplanes 1 mile of road per 42 sq miles of land 1 aircraft accident every 2 nd day 550 Communities 1 death every 9 th day in aircraft accident Need for improved Communication & Information services!

4. 4 GENERAL DYNAMICS Decision Systems Michel G, Gelinas Oct. 13, 2003 ACP WGC6/WP28 Alaska FAA Capstone Program l Part of Safe Flight 21 l State-of-the-art ground/aircraft equipment l Capstone Benefits ä Improved Situational Awareness ä Flight, Traffic and Weather Information Services ä Saves lives l Benefits limited by equipage, both on ground and in aircraft A technology designed to improve air safety. Ground technology limitations can be solved with satellites.

5. 5 GENERAL DYNAMICS Decision Systems Michel G, Gelinas Oct. 13, 2003 ACP WGC6/WP28 General Dynamics Enhancement l Satellite technology complements ground architecture. ä Use available air-to-ground link l Equip aircraft with dual mode transceivers ä UAT ä Satellite l General Dynamics technology allows for: ä Multiplexing of several aircraft on one channel ä Simultaneous voice and data on a single channel Down to earth! General Dynamics brings satellite technology …….

6. 6 GENERAL DYNAMICS Decision Systems Michel G, Gelinas Oct. 13, 2003 ACP WGC6/WP28 Satellite Complement Program l The Proof-of-Concept ä Completed March 13, 2002 l MITRE Evaluation ä Completed December 18, 2002 l Test and Evaluation ä In process l Leads to business case evaluation Satellite complement extends Benefits to remote areas.

7. 7 GENERAL DYNAMICS Decision Systems Michel G, Gelinas Oct. 13, 2003 ACP WGC6/WP28 Why Iridium Technology For Alaska? l Complete coverage of the earth, including poles l Satellites see into valleys l Cross links eliminate need for local Gateway. l Low cost hardware and service l Extensive areas without ground power, access, or comm. capability l Ideal complement to ground based system like Capstone Alaskan system exportable everywhere!

8. 8 GENERAL DYNAMICS Decision Systems Michel G, Gelinas Oct. 13, 2003 ACP WGC6/WP28 l Always on connection l Push-to-talk voice with controller l Cockpit audio panel connection l ADS, TIS, FIS l Data capable General Dynamics Technology Applied to Aircraft Use Data Under Voice allows for simultaneous transmission of voice and data over a single Iridium channel. Data Under Voice allows for simultaneous transmission of voice and data over a single Iridium channel. Netted Radio allows many aircraft to share a common channel with Controller. Netted Radio allows many aircraft to share a common channel with Controller.

9. 9 GENERAL DYNAMICS Decision Systems Michel G, Gelinas Oct. 13, 2003 ACP WGC6/WP28 Benefits to aviation community Minimizes and streamlines infrastructure investment! Iridium effectively complements ground infrastructure. Global operation Frequency coordinated Simultaneous voice & data Netted Architecture Always on Fully Integrated Gap-filler ATS benefits everywhere From surface up Oceanic PTT voice operation Automatic ADS

10. 10 GENERAL DYNAMICS Decision Systems Michel G, Gelinas Oct. 13, 2003 ACP WGC6/WP28 Multiple side Benefits l Full time communications capability can eliminate search from search & rescue operations. l Cost efficiency for ATC and users l Creates safety net ä full time communications capability l Creates convenience net ä full time satellite phone coverage capability l Improves business environment (as above) l Environmentally friendly (minimal or no ground infrastructure footprint)

11. 11 GENERAL DYNAMICS Decision Systems Michel G, Gelinas Oct. 13, 2003 ACP WGC6/WP28 The Big Picture Supports Major CAA plans. Makes business sense. Satellite complement to ground infrastructure… Ubiquitous coverage. Minimizes capital investment.
