Abstract

The University of Tokyo and Arkedge Space Inc. are now developing 6U CubeSat named ONGLAISAT in collaboration with TASA (ex-NSPO), whose main mission is Earth remote sensing. This satellite uses S-band for telemetry and command communication by 10-100 kbps and 4 kbps for each link, and X-band for mission data transfer at high speed by 36 Mbps at maximum. Moreover, it has a Store & Forward (S&F) system for one of the missions. In this paper, we summarize the communication system of ONGLAISAT which consists of the S-band, X-band, and S&F components. In particular, we discuss the benefit of installing the S&F devices as a (compact) back-up TT&C system for a CubeSat.
