Abstract

Orbital Communications Corporation has successfully launched and deployed the first two ORBCOMM satellites in April 1995. Thousands of messages have been sent to and from the satellites using subscriber communicators (SCs) (user terminals), to other SCs, Internet mail, fax machines, and pagers. The ORBCOMM system can provide the United States Armed Forces with two-way on-the-move data messaging anywhere in the world. The ORBCOMM system uses low Earth orbit (LEO) satellites instead of terrestrial fixed site relays or repeaters to provide worldwide geographic coverage. The SCs are light-weight and pocket-sized. They transmit and receive short digital burst packets, with inherent LPI/LPD
