D-1 (formerly DBSD and ICO G1)

At its launch in April 2008, D-1 (formerly DBSD and ICO G1) was the biggest commercial satellite ever launched, measuring more than 27 feet tall and weighing nearly 15,000 pounds.  Deployed, its solar arrays span more than 100 feet across, and it has a 52-foot unfurlable reflector, which opened up like an umbrella when the satellite reached its final orbit. D-1 is used to provide fully interactive mobile video, navigation and emergency assistance service, known as ICO mim™ (mobile interactive media), throughout the U.S., including Alaska and Hawaii, Puerto Rico, and the U.S. Virgin Islands.
