    Ground and Space Technology Provides
    New Solution to Global CNS Challenge!
Objective:
    Provide pilots and controllers with communications, navigation,
     surveillance (CNS) services everywhere.


Challenge:
    Existing and planned ground infrastructure limited to
     geographically defined areas with support capabilities.


Solution:
    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 !

 Why Iridium Technology For Alaska?

        Complete coverage of the earth,
         including poles

        Satellites see into valleys

        Cross links eliminate need for “local”
         Gateway.

        Low cost hardware and service

        Extensive areas without ground
         power, access, or comm. capability

        Ideal complement to ground based
         system like Capstone

                   Alaskan system exportable everywhere!

   General Dynamics Technology
   Applied to Aircraft Use
  “Data Under Voice” allows for simultaneous transmission
      of voice and data over a single Iridium channel.

       Always on connection
       Push-to-talk voice with controller
       Cockpit audio panel connection
       ADS, TIS, FIS
       Data capable

    “Netted Radio” allows many aircraft to share a common
                   channel with Controller.
