The Globalstar project was launched in 1991 as a joint venture of Loral Corporation & Qualcomm. On March 24, 1994, the two sponsors announced formation of Globalstar LP, a limited partnership established in the U.S.
Globalstar's second-generation constellation consists of 32 Low Earth Orbiting (LEO) satellites.
Globalstar's satellite constellation is simple; each satellite consists of a communications system of both S & L-band antennas, a trapezoidal body, two solar arrays & each satellite operates at an altitude of 1,414km (approximately 876 miles). 
The satellites utilize "bent-pipe" architecture. On any given call, several satellites transmit a caller's signal via CDMA technology to a satellite dish at the appropriate gateway where the call is then routed locally through the terrestrial telecommunications system.
