IKONOS Satellite
IKONOS Satellite was launched in September 1999. IKONOS panchromatic Sensor resolution is 1 m, and multispectral scanner resolution is 4 m. The swath width is 13 km at nadir. Accuracy with out ground control is 12 m horizontally, and 10 m vertically; with ground control it is 2 m horizontally, and 3 m vertically.
The orbits at an altitude of 423 miles, or 681 kilometers. Revisit time is 2.9 days at 1 m resolution, and 1.5 days at 1.5 m resolution.
IKONOS Satellite Sensor
It was a high-resolution imagery at 1- and 4-meter resolution. It collected Multispectral (MS) and Panchromatic (PAN) imagery.
