Constellation


Second-Generation Satellite Constellation

The Globalstar second-generation constellation consists of 24 Low Earth Orbiting (LEO) satellites that were finished launching in 2013.

The design of the Globalstar satellite is simple. Manufactured by Thales Alenia Space, each satellite consist of a communications system of both S and L-band antennas, a trapezoidal body, two solar arrays and operate at an altitude of 1,414km (approximately 878 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 easier system maintenance and upgrades.

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