IKONOS is a commercial earth observation satellite that collects high-resolution imagery at 1- and 4-meter resolution. It offers multispectral (MS) and panchromatic (PAN) imagery. It provides imagery beginning January 1, 2000. The company Space Imaging, Inc. distributes IKONOS imagery under the product name CARTERRA.
History
IKONOS comes from the Greek word for "image". Ikonos-1 was planned for launch in 1999 but the launch failed. Ikonos-2 was planned for launch in 2000, but was renamed Ikonos and was launched on September 24, 1999 to replace Ikonos-1. The imaging sensors are panchromatic and multispectral . This satellite has a polar, circular, sun-synchronous 681-km orbit and both sensors have a swath width of 11 km.
