Our laboratory supports two design projects for undergraduate students. One is the desgin project of future space systems supervised by Prof. Miyazaki, and the other one is that of nano satellites supervised by Prof. Yamazaki except NEXUS (NEXUS is supervised by Prof. Miyazaki). You can see the detail of the nano-satellite development project at the website of Prof. Yamazaki's group

CESS is a student design group that has been establshed since April, 2017. The objective of CESS is to propose a cuttinge-edge space systems. The students study on the misgion design, the spacecraft design to achieve the mission, and demonstrate the mission using a conceptual model.

The proposal of novel gossamer space structure such as solar sail, self-deployable starahde, and membrane space solar power system is one of the prior projects in CESS.

Nano-Satellite Development Project

Our college established College of Science and Technology Future Doctor Lab (CST Mirai-Hakase-Kobo) in 2007. Our laboratory started the nano-satellite development project in 2001, and joined the Mirai-Hakase-Kobo in 2007. In 2015, our department formed "Aerospace Lab" that is the consortium of several projects in the department, and the Satellite Lab has been managed by Prof. Yamazaki since that time. The history of Satellite Lab until 2015 is summarized in other web page.

Our laboratory/Satellite Lab has launched three satellites and is developing one satellite. You can see the overview of each satellite if you click the satellite name in the table below.

SEEDS 1U CubeSat launched in July 2006. Our first satellite. SEEDS was not injected into the orbit because the rocket had some trouble in the first engine.
SEEDS-II 1U CubeSat launched in April 2008. The launch was successful and SEEDS-II is now under late operation phase.
SPROUT 20cm class (8U) CubeSat launched in May 2014. The launch was successful, and the deployment mission of the combined membrane structure was conducted in June 2016. The attitude determination and control mission was conducted between 2014 to 2016. After the two and half year's operation, SPROUT had a trouble with the receiveing subsystem. SPROUT has not been accept the uplink command since mid of September, 2016. We guess the reason is the trouble of the receiving antenna or relating electric circuit. SPROUT is programed so that it stops the downlink if it has not received the uplink command for about 1 month. Therefore, SPROUT stopped the downlink in the end of October 2016. We guess the electric power of SPROUT is tuened on still now, so we have been sending the uplink command periodically to recover SPROUT.
NEXUS 1U CubeSat under development with JAMSAT. An amateur satellite equipped with a transponder. NEXUS has been selected as one of the Innovative satellite technology demonstration program, and will be launched by Epsilon rocket #4 in FY2018.
