Satellite  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 DigitalGlobe’s constellation. In April of 2011, DigitalGlobe 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, DigitalGlobe’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.
