Specification
IKONOS:
The IKONOS
satellite is the world’s first commercial satellite to collect
panchromatic (black-and-white) images with .80 m resolution and
multispectral (color) imagery with 3.2-meter resolution. Imagery from
the panchromatic and multispectral sensors can be merged to create .80 m
color imagery (pan-sharpened). IKONOS imagery is being used for national
security, military mapping, air and marine transportation, and by
regional and local governments. From a 423-mile-high orbit, IKONOS has a
revisit time of once every three days and downlinks directly to more
than a dozen ground stations around the globe.

QUICKBIRD
The
QuickBird satellite is the first to orbit Earth in Maxar’s
constellation. In April of 2011, Maxar completedan orbit
raise designed to extend the mission life of the QuickBird sensor.
An operational altitude of 482 km was achieved with an expected
gradual descent to 450 km by early 2013. Today, Maxar’s
QuickBird satellite offers sub-meter resolution imagery, high
geolocational accuracy, and large on-board data storage. With global
collection of panchromatic and multispectral imagery, QuickBird is
designed to support a wide range of geospatial applications.

WORLDVIEW-1
WorldView-1,
launched September 2007, is the first of our next-generation
satellites—the most agile satellites ever flown commercially. The
high-capacity, panchromatic imaging system features half-meter
resolution imagery. Operating at an altitude of 496 km, WorldView-1
has an average revisit time of 1.7 days and is capable of collecting
over one million km2 per day of half-meter imagery. The satellite is
also equipped with stateof-the-art geolocation accuracy capabilities
and exhibits stunning agility with rapid targeting and efficient
in-track stereo collection. WorldView-1 is currently on the move.
Over the course of two years the orbit will be adjusted to achieve a
descending node of 1:30pm.

WORLDVIEW-2
WorldView-2, launched October 2009, is the first high-resolution
8-band multispectral commercial satellite. Operating at an altitude
of 770 km, WorldView-2 provides 46 cm panchromatic resolution and
1.85 m multispectral resolution. WorldView-2 has an average revisit
time of 1.1 days and is capable of collecting up to 1 million km2 of
8-band imagery per day, greatly enhancing Maxar’s
multispectral collection capacity for more rapid and reliable
collection. WorldView-2 substantially expands imagery product
offerings to all Maxar customers.

GeoEye-1
The
GeoEye-1 satellite is equipped with some of the most advanced
technology ever used in a commercial remote sensing system. The
satellite collects images at .41-meter panchromatic
(black-and-white) and 1.65-meter multispectral resolution. The
satellite can collect up to 350,000 square kilometers of
pan-sharpened multispectral imagery per day. This capability is
ideal for large-scale mapping projects. GeoEye-1 can revisit any
point on Earth once every three days or sooner.
