SEIRIOS Satellites

Two CubeSats reflect the light from a celestial body and the micro-sat combines the two light to observe interferometric fringe with densified pupil spectroscopy interferometer.

SEIRIOS is a pathfinder mission to demonstrate the formation flying space infrared interferometer with densified pupil spectroscopy. SEIRIOS is constructed by one 40-kg class micro-satellite and two 10-kg class 6U CubeSats.

Space infrared interferometer with densified pupil spectroscopy by three satellites. Wave length: 0.7-1um. Aperture diameter : 5cm.

Launched in docking. Initial operation and calibration are executed in docking form. After the calibration, the two Cubesats separate and start formation flying control to get interferometric fringe. The three satellites will form along-track straight line formation for formation flying interferometer demonstration.

The micro-satellite is placed at the center of the two CubeSats, and the CubeSats keep a constant distance between 5 to 50-m from the micro-satellite. Two CubeSats reflect the light from a celestial body and the micro-sat combines the two light to observe interferometric fringe with densified pupil spectroscopy interferometer.

As an extra success, we targets high-resolution imaging of solar system object like Europa by multiple interferometric fringe data at the multiple point in the UV-plane.
