IkonosIKONOS 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. Specifications Communications IKONOS conducts telemetry, tracking and control in the 8345.968-8346.032 MHz band (downlink) and 2025-2110 MHz band (uplink). Downlink data carrier operates in the 8025-8345 MHz band. Spatial Resolution - 1-meter panchromatic (1-m PAN)
- 4-meter multispectral (4-m MS)
- 1-meter pan-sharpened (1-m PS)
Spectral Resolution | -m PAN | 4-m MS & 1-m PS | | (Blue) | 0.45-0.90 m | 0.445-0.516 m | | (Green) | * | 0.506-0.595 m | | (Red) | * | 0.632-0.698 m | | (Near IR) | * | 0.757-0.853 m | Temporal Resolution The revisit rate for IKONOS is 3 to 5 days off-nadir and 144 days for true-nadir.
