Globalstar satellites use simple and proven technology. Each satellite consists of an
antenna, a trapezoidal body, two solar arrays and a magnetometer, and operates at an
altitude 1414km (876 miles).

Globalstar successfully launched its entire satellite constellation over the course of three
years, 1998 - 2000. The constellation is made up of 48 operational satellites and four
in-orbit spares.

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 infrastructure.

The satellites are placed in eight orbital planes of six satellites each, inclined at 52 degrees
to provide service on Earth from 70 degrees North latitude to 70 degrees South latitude.
