The
GeoEye-1 satellite is equipped with the
most advanced technology ever used in
a commercial remote sensing system. The
system provides images at nadir with
0.5-meter panchromatic (black & white)
and 2-meter multispectral resolution.
Just as important, 3 meters of inherent
geolocation accuracy has never before
been achieved in any commercial imaging
system.
A polar orbiting satellite, GeoEye-1
orbits the Earth 15 times per day flying
at an altitude of 681 kilometers with
an orbital velocity of about 7.5 km/sec.
Its sun-synchronous orbit allows it
to pass over a given area at about
10:30 a.m. local time every day. Industry-leading
agility means the entire satellite
turns and swivels very quickly in its
orbit to aim the sensor at areas directly
below, as well as from side-to-side
and front-to-back, enabling it to collect
more imagery during a single pass
GeoEye-1 will be able to revisit any
point on Earth once every three days
or sooner. The satellite collects up
to 700,000 square kilometers of panchromatic
(and up to 350,000 square kilometers
of pan--sharpened multispectral) imagery
per day.
