Second-Generation Satellite Constellation

The Globalstar second-generation constellation will consist of 24 Low Earth Orbiting (LEO) satellites.

The Globalstar satellite is simple; Each consists of a communications system of both S and L-band antennas, a trapezoidal body, two solar arrays and each satellite operates at an altitude of 1,414km (approximately 876 miles). The second-generation satellites are manufactured by Thales Alenia Space.

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.

The system's software resides on the ground, not on the satellites, which means fast and easier system maintenance and upgrades.

The Satellite Operations Control Center (SOCC) manages the Globalstar satellite constellation.
