History of Iridium

Take a look back at Iridium’s unique history, from its early days within Motorola, through its infamous bankruptcy, to the rise of the global corporation that Iridium became.



The Birth of Iridium

01 01 1987 Company Milestone

The Concept for the Iridium Global Constellation is Born

Motorola Strategic Electronics Division engineers Bary Bertiger, Ken Peterson, and Ray Leopold began plotting an outline for what would later become the first global satellite communications network – Iridium. The Iridium concept, conceived in 1987 in Chandler, Arizona, envisioned a satellite-based telephone system that would have commercial applications and that would provide worldwide coverage using one handheld, portable device. This became what was ultimately known as the “Iridium System.”

07 14 1988 Company Milestone

The First Draft of the Iridium Constellation is Created

The “Global Personal Satellite Communications System” was the first draft of the Iridium constellation created by Bary Bertiger, Ken Peterson, and Ray Leopold. The original one-page document, which was later included in the patent filing, now sits in the Smithsonian National Air and Space Museum in Washington D.C.

Motorola filed an application with the U.S. Federal Communications Commission (FCC) for the deployment of the Iridium system.

06 14 1991 Business Update

Motorola Incorporates Iridium, which becomes Iridium Inc.

Motorola established Iridium Inc. as a separate entity from Motorola SatCom to develop and deploy the satellite network. Besides Motorola, which retained a 20.1 percent ownership stake, other major partners included Germany’s Vebacom (10 percent), Korea Mobile Telecommunications (4.4 percent), Sprint Corporation (4.4 percent), and Italy’s STET (3.8 percent).

01 01 1992 Company Milestone

The Iridium Constellation is Redesigned for 66 Satellites

At conception, the Iridium constellation was thought to need 77 satellites to provide truly global coverage to the planet. In 1992, the plan was redesigned to include just 66 satellites after engineers discovered they could do the job. Although the company was named for the 77th element on the periodic table, the name Iridium stuck with the final system.

08 01 1992 Industry

FCC Grants an Experimental License for the Iridium System

An experimental license was granted by the U.S. FCC to construct and launch five demonstration satellites Iridium planned for launch in 1997. In the same year, the World Administrative Radio Conference (WARC) decided to work towards establishing guidelines to regulate worldwide radio spectrum rights and facilitate the building of Iridium systems.

07 29 1993 Business Update

Iridium Stock Transferred from Motorola to Private Investors

Iridium Inc., the consortium of investors involved in the Iridium project, issued an invitation for additional private equity investment, and in July 1993, stock previously belonging to Motorola was transferred to private investors. Subsequently, Iridium Inc. issued a $3.37 billion contract to Motorola’s Satellite Communications Division to purchase the rights to the Iridium space system. In addition, an agreement was executed with Motorola for operation and maintenance of the Iridium system after initial satellite deployment.

Phoenix Rising

07 31 2000 Company Milestone

Iridium Satellite LLC is Founded in Anticipation of Acquisition

Iridium Satellite LLC was formed with the intent to later purchase the assets of Iridium LLC from bankruptcy and re-start the business. This company would go on to become the successful organization that still owns and operates the world’s only truly global satellite network today.

11 16 2000 Business Update

Bankruptcy Court Approves Purchase of Iridium LLC

After declaring bankruptcy in 1999 and with the planned deorbit of the Iridium constellation by the end of 2000, Iridium LLC’s assets were approved for purchase by a bankruptcy court. Although the Iridium satellites and other assets are estimated to have cost around $6B, the investors bought the firm for approximately $25M. As part of the initial cost-cutting efforts to help Iridium rebound, Iridium Satellite LLC contracted with Boeing to operate and maintain the satellite constellation, who did the job for $3.5M per month, compared to Motorola, who was charging the company $45M per month for the same services. At the time of this purchase, Iridium planned to relaunch service within 60 days. Ultimately, commercial service relaunched on March 30, 2001.

12 05 2000 Company Milestone

U.S. Government Saves the Iridium Constellation with a Contract


Days before the planned deorbiting of the Iridium satellite constellation, the U.S. Department of Defense awarded Iridium Satellite LLC a $72M contract for 24 months of unlimited airtime for 20,000 government users on the Iridium Network. The contract, awarded through the DoD’s Defense Information Systems Agency, included options that would expand the contract to 2007, bringing its total value to $252 million.
