The Globalstar communications network provides real-time digital, voice, data, and fax capabilities to people around the world. Prime contractor Space Systems Loral and sub-contractor Thales Alenia Space built the satellites in Rome, Italy.
The satellites were rocketed into space on three lower stages of the Soyuz launch vehicle. After the last lower stage separated, the Fregat upper stage then properly placed the satellites into a Low-Earth Orbit (LEO) of 920 kilometers (570 miles), with an orbital inclination of 52 degrees, at 22:18 UTC.
The services provider for the launch is Russian-European organization Starsem, which consists of a group of space organizations: Arianespace, EADS SPACE, Russian Federal Space Agency, and The Samara Space Center [TsSKB-Progress])
These four Globalstar satellites, along with four other satellites due to be launched later in the year, will be added to the company’s current fleet of first-generation LEO satellites. The Globalstar second-generation fleet of satellites (Globalstar II) is expected to start launching in late 2009.
Multiple satellites can be launched from one rocket due to its trapezoidal shape and deployable solar panels. The two solar arrays provide 1,100 Watts of electrical power used under normal operations. Each satellite weighs approximately 450 kilograms (990 pounds) on the Earth’s surface, with a dry mass of 350 kilograms (770 pounds). They are each designed to last for about seven-and-one-half years.
