Satellite Remote Sensing IKONOS
IKONOS is derived from the Greek word for "image." The IKONOS satellite is the world's first commercial satellite to collect black-and-white images with 1-meter resolution and multi-spectral imagery with 4-meter resolution.
IKONOS is similar to aerial photography in its clarity and resolution and can be used for a similar wide-ranging set of applications. These applications include urban planning, environmental monitoring, mapping, natural disaster assessment, telecommunications network planning, oil and gas exploration, and agricultural monitoring.
The IKONOS satellite orbits the Earth every 98 minutes at an altitude of approximately 680 kilometers or 423 miles. IKONOS was launched into a sun-synchronous orbit, passing a given longitude at about the same local time (10:30 am) each day. IKONOS can produce 1-meter imagery of the same geography every three days.
