∎ STSAT-3
The STSAT-3 is a low Earth orbit satellite used for space observation and space technology verification in a sun-synchronous orbit of altitude 600km. The main MIRIS (Multi-purpose Infra-Red Imaging System) payload conducts infrared observation of the earth and space while the sub-payload, COMIS (COMpact Imaging Spectrometer), monitors changes in the earth environment.
Additionally, STSAT-3 uses advanced space technologies such as lightweight composite materials, a Hall thruster, an array antenna, Lithium-Ion Batteries, and a multi-functional structure.
- To conduct cosmic infrared background observation and earth exploration
- To conduct infrared earth observation, atmosphere observation and environment monitoring
- To verify space technologies and conduct experiments to develop next-generation technologies
- To develop and test next-generation core space-based technology for application-level satellites
