The unique geometry of Iridium's low-earth
orbiting (LEO) satellites provides global
coverage, including the extreme Polar Regions
that are not covered by geostationary satellite
systems. The low satellite orbits permit
communications using compact handheld
satellite phones or fixed installations with very
small external antennas. The voice quality is
sharp and clear, without the delays and echoes
commonly experienced with higher-orbit
satellites. The Iridium satellite constellation
consists of 66 operational satellites and 11
spares, which the company can activate to
replace an unserviceable satellite at any time.
The 66 satellites are organized into six orbital
planes. They are in near-polar orbits at an
altitude of 485 miles (780 km) above the earth.
They circle the earth once every 100 minutes
traveling at a rate of 16,832 miles per hour
(27,070 kph). Each satellite has a footprint of
about 2,800 miles.
