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 ! 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!Alaskan system exportable everywhere!
