TRICOM 1, 1R (Tasuki)

TRICOM 1 [University of Tokyo]

TRICOM 1 is an experimental 3U Cubesat built at the University of Tokyo.

TRICOM 1 is a 3 kg spin stabilized satellite featuring a store and forward communication equipment and an earth imaging camera. The CubeSat is launched without the usual deployer and is base mounted on the launch vehicle without the usual guiding rails or tabs.

The Store and forward mission is to collect the data that is transmitted from the ground terminal while orbiting the Earth, transfer the data at the direction of the ground station.

The earth imaging mission is to use four main cameras and a sub-camera during the initial operation to allow imaging the ground even in an unstable state.

The satellite was the payload of the experimental SS-520 (3 stg) nano-satellite launcher. It is to be put into an 180 km × 1500 km orbit with 31 inclination in 2017. It failed to reach orbit.

A reflight as TRICOM 1R was successfully conducted in February 2018. After reaching orbit, it was renamed Tasuki.
