Overview & HistoryIKONOS SpecificationsPricing

IKONOS is the world’s first high-resolution commercially-available satellite with imagery exceeding 1-meter (m) resolution. Launched into space on September 24, 1999 from a pad at Vandenberg Air Force Base, CA, IKONOS was originally owned by Space Imaging and is now a part of GeoEye’s constellation of high resolution satellites.

IKONOS features 82-centimeter (cm) panchromatic and 3.28-m 4-band multispectral resolution (i.e. blue, green, red and near-infrared/NIR). It orbits our planet at 681 kilometers (km), or the approximate distance from Los Angeles to San Francisco, CA. Until 2007, IKONOS was the industry’s most agile satellite with the ability to image large sections of earth every 3 days.
