Further Examination of Iridium Satellite Phone and Pager System for Military Use

Abstract

The Iridium satellite-based personal communications system (PCS) has been offering voice and messaging services since November 1998 and March 1999 respectively. With its interconnected constellation of 66 low earth orbit (LEO) satellites, Iridium is capable of providing continuous communications anywhere in the world. This Technical Memorandum describes further evaluations of the Iridium system carried out by the Military Satellite Communications group at Defence Research Establishment Ottawa (DREO). Evaluations include additional voice service test at high latitudes, voice service tests with an Airsat1 terminal, messaging service evaluation, three-way conference calling over Iridium, and propagation delay tests over the voice circuit.
