Abstract:

Iridium is the first satellite-based personal communications system offering global service via an interconnected constellation of low earth orbit LEO satellites communicating directly with handheld terminals. The total constellation of satellites was launched over a 12-month period ending May 1998. Voice service commenced in November 1998 followed by paging services in March 1999. This Technical Memorandum describes an evaluation of the Iridium paging service carried out by the Military Satellite Communications MSC Group at Defence Research Establishment Ottawa DREO during the period March to June 1999. Paging tests were performed under two principle scenarios stationary and inflight paging. Performance parameters observed include delivery time and message error performance.
