The Osaka Prefecture University Satellite, or OPUSAT was a technology demonstration cubesat built and operated by Japan's Osaka Prefecture University. It had a size of 100x100x100mm (without antennas and solar paddles) and build around a standard 1U cubesat bus. The primary satellite purpose is the space testing of the power system based on a Lithium-ion capacitor. The tests were largely successful,[3] and it finished operation by reentry to Earth atmosphere on 24 July 2014. The OPUSAT is a development successor to “Maido Ichigo” satellite by East Osaka Craftmen Astro-Technology SOHLA in Osaka.
