Dulles - June 19, 1998 - Orbital Sciences has shipped eight OrbComm communications satellites to the company's launch vehicle facility at Vandenberg Air Force Base, California, where integration for a Pegasus launch in mid-July has begun.
Orbital is building and launching a total of 36 low-orbit satellites for its OrbComm Global, L.P. (OrbComm) affiliate, which is developing the world's first "Little LEO" data communications constellation designed to allow businesses and individuals to send and receive short, low-cost messages anywhere on Earth. The upcoming Pegasus launch will bring the total number of in-orbit OrbComm satellites to 20.
The OrbComm satellites are based on Orbital's flight-proven MicroStar(TM)
spacecraft platform. MicroStar serves as the basis for a total of 14
satellites now in orbit, including spacecraft for OrbComm, ORBIMAGE and
Teledesic. The MicroStar platform is uniquely designed to be launched in
multiple or "piggyback" units aboard the company's Pegasus rocket by arranging the disc-shaped satellites in a stacked configuration. The OrbComm satellites that were shipped by Orbital each weigh approximately 90 pounds and are designed with an expected operational life of eight years.
A joint venture between Orbital and Teleglobe Mobile Partners, OrbComm is
the world's first mobile satellite services provider to offer two-way data and messaging communications. The OrbComm system is fully licensed by the
U.S. Federal Communications Commission and is currently providing
communications services throughout North America. OrbComm has also been
granted spectrum worldwide by the International Telecommunications Union and has established service distribution arrangements in 100 countries around the world.
