Constellation
The Globalstar constellation consists of 40 Low Earth Orbiting (LEO) satellites, with an additional four satellites in orbit as spares.
The Globalstar satellite is simple; Each consists of an antenna, a trapezoidal body, two solar arrays and a magnetometer, and operates at an altitude of 1,414km (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.
The system's software resides on the ground, not on the satellites, which means fast and easy system maintenance and upgrades.
The Satellite Operations Control Center (SOCC) manages the Globalstar satellite constellation.
