History of artificial satellite "TeikyoSat" development

Steps to the birth of the artificial satellite "TeikyoSat-4"

The TeikyoSat project started in 2008. The first "TeikyoSat" was a nano-satellite model the size of an empty can. Since then, the engineering club "Space Systems Research Group" was established at the initiative of Faculty of Science and Engineering Department of Aerospace Engineering Professor Hirotoshi Kubota (at the time), and the group made steady progress step by step, winning the JSME Prize at the 18th Satellite Design Contest in 2010, and in 2011 being selected to carpool on the H2A launch vehicle to be launched by JAXA. In February 2014, after five years in space, TeikyoSat-3 flew 400 km above the ground and continued to transmit HK data necessary to operate, maintain, and manage the satellite for about three months, but was unable to complete its mission to observe microbes because it could not receive radio signals from the earth. However, the satellite was unable to complete its mission to observe microorganisms because it could not receive signals from Earth. TeikyoSat-4, which was developed as a successor to TeikyoSat-3 based on the data obtained through the development and operation of TeikyoSat-3, was launched into space in November 2021 aboard JAXA's Epsilon 5 rocket.

Developed by the engineering club "Space System Study Group"

"Graduate School of Space Systems"

The Space Systems Research Club is an engineering club led by Associate Professor Masaaki Kawamura of the Department Department of Aerospace Engineering of Science Faculty of Science and Engineering. It was founded in 2009 based on Professor Kubota's desire for students to realize the power of science by building and launching satellites with their own hands. Starting out with no prior knowledge, the club has overcome each challenge one by one by visiting laboratories both on and off campus to learn know-how and obtaining cooperation from companies in the prefecture.
