• Satellite Constellation

    Satellite constellation with small or microsatellites is a rising concept in the recent space industry. Unlike the traditional single satellite mission, satellite constellation can achieve rapid revisit time as well as enhanced coverage ability, which makes the scope of satellite mission goes further. Designing orbital patterns for satellite constellation has been studied to obtain efficient configuration for mission-specific objectives. Also, constellation deployment and maintenance strategy are one of the essential parts for effective mission operation.


  • Scanning the EARTH SAR & OPTICS

    As the miniaturization of satellites progresses, Earth observation using microsatellites is emerging worldwide.
    The cost of producing the micro-satellites has been greatly reduced compared to the existing satellites, and efficient mass production is possible through platform development.
    In addition to the sale of mass-produced platforms for satellites, the satellite market is becoming active with the provision of Earth observation service.
    This study aims to lay the groundwork for platform development for satellite mass production by designing the micro-optical satellite and micro SAR satellite system according to global satellite development trend.
    Micro-optical satellites are expected to build a low-cost Eart observation system.
    Micro SAR satellites are expected to be able to build all-weather observation systems that are not affected by the observation environment.

  • Vision-based Autonomous Rendezvous and Docking

    CANYVAL-C mission is aimed at scientific validation of photographing the sun’s corona.
    This mission is the application of Virtual Telescope technology that uses several discrete satellites as a space telescope.
    The mission requires development of inertial alignment hold technology, spacecraft formation flying GNC technology and inter-satellite link technology.
    CANYVAL-C is a subsequent mission of CANYVAL-X, technical experiment mission of virtual telescope, and expects further projects of solar science and X-ray objective science mission.

    The CANYVAL-C system consists of two CubeSats, ‘PUMBAA’ and ‘TIMON’. PUMBAA, the occulter, is a 2U CubeSat that covers the sun for corona imaging.

    TIMON, the detector, is an 1U CubeSat that takes a coronagraph with an optical camera.
    The CubeSats are planned to be launched in July, 2019.
