Globalstar System
Presentation
The Globalstar System
Globalstar is a satellite voice and data communications network based on
a Low Earth Orbit (LEO) constellation of 40 operating satellites.
How a call is managed
1.
User or modem dials the
desired number
The call is routed to the
nearest satellite overhead
The satellite then routes the
call to the nearest ground
station / gateway
The call is sent through the
local terrestrial network to
its final destination

Globalstar Communication
reliability
The Globalstar system is reliable; each terminal connects with up to three different
satellite at the same time, automatically and continuously choosing the one
with the better signal; this is valid for voice and data communications.

Global Coverage
Globalstar Data Services
The Globalstar Modem, is like any commercial
standard modem, and can be integrated with any
system that supports std Hayes AT commands.
It permits Asynchronous and packet data
communication at 9,6 Kbps uncompressed; specific
software applications that are available may
substantially increase data throughput

Globalstar Italian references
The Globalstar Satellite communication has been chosen by many of the major Italian
companies and organizations to operate as primary system in all those zones away
from GSM coverage, and as a alternative system under GSM coverage, for providing
the necessary voice and data communication.
