Observation Range of Water Resources Satellites
- (Peninsula Observation) The satellite orbits the Earth in a polar (sun-synchronous) orbit at an altitude of 561 km and images the Korean Peninsula twice a day. *Full coverage of the peninsula can be obtained after three days of imaging.
- (Global Observation) The satellite can monitor key strategic countries overseas, including in Asia, Africa, and South America. *It can cover more than 65% of major countries in Southeast Asia, Africa, and South America.
