Development of a 6U CubeSat in cooperation with National Space Organization in Taiwan


In order to verify the functions and payload design required for the "Intelligent Remote Sensing Satellite Constellation with Ultra High Resolution" mission in the Third Phase National Space Program, National Space Organization (NSPO) of National Applied Research Laboratories (NARLabs) proposed the "6U Fast Validation CubeSat" Project (hereinafter referred to as the project) and cooperated with Professor Shinichi Nakasuka's laboratory in the Department of Aeronautics and Astronautics of the University of Tokyo, Japan's Space Edge Lab.Co., Ltd., and Japan's Space BD, Inc. to jointly develop, manufacture, launch, and operate a 6U-class CubeSat. The proposal for this cooperative satellite project has been reviewed and approved by NSPO and the satellite is expected to be launched from the International Space Station in 2022.

The project provides a fast validation platform to test optical sensors developed by NSPO. Based on the past successful experience of CubeSat technology by Professor Shinichi Nakasuka's team, the Japanese side quickly developed a low-cost CubeSat-level medium-resolution remote sensing satellite, combining the remote sensing payload developed by Taiwan and the satellite bus developed by Japan. This design is expected to have a wide range of applications and commercial uses, including high-efficiency and high-frequency disaster monitoring and environmental monitoring, and it also can ensure the reliability of future satellite missions.

The project uses the remote sensing payload developed by NSPO as the pioneer design of "Intelligent Remote Sensing Satellite Constellation with Ultra-High Resolution" in the "Third Phase National Space Program". Using the sensor and new optical design made by the NSPO team, the satellite bus contains the attitude control function developed by the Japanese team and the development experience of many successful CubeSats in the past. Based on the well-founded CubeSat attitude control functions, reliability management, and ground operation system of Professor Shinichi Nakasuga's laboratory at the University of Tokyo, combined with the NSPO's past experience in developing remote sensing payloads, the time and cost required for developing, manufacturing, and operating medium-resolution Earth observation satellites will be greatly reduced.
