IKONOS

The IKONOS satellite was the world’s first commercial satellite to collect panchromatic images with 80 cm resolution and multispectral imagery with 3.2 meter resolution. It was decommissioned in March 2015 ending a 15 year mission life.

Imagery from the panchromatic and multispectral sensors could be merged to create 80 cm pan-sharpened color imagery.

IKONOS imagery was used for national security, military mapping, air and marine transportation, and by regional and local governments.

The satellite had a revisit time of once every three days and downlinked directly to more than a dozen ground stations around the globe.
