    ∎ 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.


    Objectives
    - 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
