Integrator’s Reference Manual

Space Segment

The space segment consists of 48 LEO satellites (and eight additional in-orbit spares) built by Loral Space Systems and operated by Globalstar Limited Partnership (GLP) in San Jose, CA.

Compared to medium-Earth-orbit or geostationary- Earth-orbit (MEO/GEO) satellites, LEO satellites offer several advantages: minimal delay (~250 ms or comparable to terrestrial digital cellular), multi-satellite handoff, extremely small antenna, lower power consumption, and lower cost.

Ground Segment

The ground segment consists of Earth stations called Gateways, which provide service in specific geographical areas. The Gateways are deployed worldwide and communicate via C-band frequencies to/from the LEO satellites, which serve as “bent pipe” transponders.

User Terminals communicate to/from a Gateway ground station using L- and S-band frequencies, via the LEO satellites.

A User Terminal can be either a QUALCOMM Globalstar

GSP-1600 Tri-Mode Phone, or QUALCOMM Globalstar

GSP-1620 Satellite Data Modem.
