Chapter 1
Where the Story Begins
Public biographical detail about Bertiger’s early life is limited. His best-documented historical role is as a Motorola engineer associated with the original Iridium concept.
Chapter 2
The Challenge
Design a global mobile communications system using satellites close enough to Earth for handheld devices to reach them.
Chapter 3
The Turning Point
Bary Bertiger, Ray Leopold, and Ken Peterson developed the early Iridium concept at Motorola in the late 1980s, leading to a global LEO constellation architecture.
Chapter 4
What Changed
Iridium demonstrated that large low-Earth-orbit communications constellations could provide worldwide mobile coverage.
Chapter 5
TransitSatellite Connection
Iridium is an important predecessor to modern LEO constellations such as Starlink and other global broadband networks.
