IKONOS is a commercial earth observation satellite, and was the first to collect publicly available high-resolution imagery at 1- and 4-meter resolution. It offers multispectral (MS) and panchromatic (PAN) imagery. The IKONOS launch was called “one of the most significant developments in the history of the space age”. IKONOS imagery began being sold on January 1, 2000.
It derived its name from the Greek term eikōn for image.
IKONOS was originated under the Lockheed Martin Corporation as the Commercial Remote Sensing System (CRSS) satellite. On April 1994 Lockheed was granted one of the first licenses from the U.S. Department of Commerce for commercial satellite high-resolution imagery. On October 25, 1995 partner company Space Imaging received a license from the Federal Communications Commission (FCC) to transmit telemetry from the satellite in the eight-gigahertz Earth Exploration Satellite Services band. Prior to launch, Space Imaging changed the name of the satellite to IKONOS. IKONOS comes from the Greek word for "image".
