High Resolution Commercial Imagery:
Ushering In a New Era for Defense Customers
Until recently, only select governments had access to high-resolution
satellite imagery of the earth. DigitalGlobe, an imagery and information
company located in Longmont, Colorado, USA, brought sub-meter space-based
imagery to the commercial market aboard the QuickBird satellite on October
18, 2001. It is the highest-resolution commercial imaging satellite in
operation, collecting images showing details never before seen from a
commercial imaging satellite. QuickBird was manufactured by Ball Aerospace &
Technologies Corp., and successfully launched from Vandenberg AFB in
California aboard a Boeing Delta II. QuickBird circles the Earth in a 450-km
(280-mile), 98-degree sun-synchronous orbit, which provides consistent 3-4
day revisit times year-round.
QuickBird has two sensors on board capable of collecting 61-centimeter
panchromatic (black and white) sensor and 2.44-meter 4-band multispectral
imagery-both are collected every time an image is acquired. Moreover, the
panchromatic and multispectral imagery can be fused to form a color 61-cm
image in either three or four bands. The satellite produces imagery that is
spatially and spectrally very accurate, while providing an industry-leading
16.5-kilometer (10.3-mile) wide swath width. A variety of imagery products
are available, ranging from raw uncorrected data to orthorectified products
suitable for mapping applications.
Security Applications of QuickBird Imagery
DigitalGlobe's high-resolution QuickBird imagery provides a capability to
address a myriad of security issues never before commercially available from
a space-based imaging platform. The following are some of the security
applications that can be addressed with QuickBird imagery:
- Ground Force Assessments. The imagery permits generic
identification of most armor and support vehicles (e.g., differentiating
between tanks, armored personnel carriers, and self-propelled artillery),
and specific identification for some vehicles.
- Naval Force Assessments. All naval vessels (combatants and
support vessels) are identifiable by specific class using the panchromatic
data. This includes identification of major offensive and defensive
weapons systems, ship superstructures, antennas, and even mooring lines.
- Air Force Assessments. Classification of all military aircraft
is possible, enabling analysts to tell the difference between similar
aircraft (excluding variants).
- Air Defense Assessments. The imagery enables identification of
mobile and fixed surface-to-air missiles-it is possible to determine if a
launcher is loaded-as well as anti-aircraft-artillery (AAA) formations.
- Military Facilities Assessments. QuickBird imagery is useful in
conducting facility analysis, including identification of facility
subcomponents by specific functionality. The imagery supports monitoring
of force deployments, conducting order-of-battle assessments, and
detecting change in facilities over time (multispectral imagery also plays
an integral role in accomplishing the latter).
- Weapons Storage Assessments. QuickBird imagery provides
critical information on weapons storage facilities, including bunker
construction techniques, differentiating storage types, and identification
of transshipment facilities.
- Strategic Industries Assessments. The imagery supports
identification of key strategic industries such as energy, extraction, and
manufacturing facilities, including assessments of production capacity and
inventory.
- Infrastucture Assessments. Lines of communication, including
roads, rails, airfields and port facilities are readily extracted from the
imagery. Specifically, road features (alignments, lanes, centerlines, and
surface) are identifiable. Rail infrastructure characteristics (including
gauge and capacity) are readily distinguishable. All airfield components
(runways, taxiways, radars, lighting, and surface markings) are
identifiable on the 61-cm imagery, as are all port components (e.g.,
gantry cranes, mobile gantries, and conveyors).
- Illicit Crop Analysis. The combination of 61-cm panchromatic
and 2.44-m multispectral QuickBird imagery greatly aids identification of
illicit crops, help support yield estimates, and provide a means of
monitoring eradication efforts.
In summary, DigitalGlobe's QuickBird satellite-the world's
highest-resolution commercial imaging satellite-provides a significant means
to address security requirements across a broad range of needs. Commercial
availability of this imagery through DigitalGlobe allows government defense
users ready access to a powerful tool that supports baseline assessments,
mission planning, and operations.
