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.
