About
KOMPSAT-5 is a Korean satellite launched in 2013 as part of the Korean National Development Mission Plan by the Ministry of Education, Science and Technology. Developed by the Korean Aerospace Research Institute (KARI), the primary objective of KOMPSAT-5's mission was to monitor for environmental disasters with the use of SAR (Synthetic Aperture Radar) imaging.
KOMPSAT-5 carries three instruments: Korea SAR Instrument (COSI), the Atmosphere Occultation and Precision Orbit Determination (AOPOD), and the Laser Retro-Reflector Array (LRRA). With the COSI instrument, it provides SAR imagery in varying resolution and swath widths. KOMPSAT-5 operates in a sun-synchronous orbit of an altitude of 550 km with an orbital period of 98.5 minutes, and a repeat cycle of 28 days.
Environmental Disaster Monitoring
Land surface SAR imagery, Atmospheric specific humidity, Atmospheric temperature, Land surface topography.
Wide Swath
Width
Multiple Swath widths between 5km and 100km, allowing for large-area coverage in a single pass.
High-Resolution
Imaging
High-resolution optical imaging data, enabling detailed observations of Earth's surface.
Features and Benefits
- COSI provides viewing of landscape topography and multi-purpose land imagery for land applications of cartography and disaster monitoring.
- KOMPSAT-5 is also referred to as the 'GOLDEN' mission due to; Acquisition of independent high resolution SAR imagery, ocean and land management (survey of natural resources) and disaster and environmental monitoring (Surveillance of large-scale disasters and its countermeasure).
