The OPUSAT CubeSat, built by students at the Osaka Prefecture University Small Spacecraft Systems Research Center (SSSRC), will test Lithium-Ion Capacitors in space.
Lithium-Ion Capacitors have a high energy density (reportedly 14 Wh/kg) and so could potentially be of use in small satellites such as CubeSats where space and mass are at a premium.
OPUSAT will have deployable solar panels and Maximum Power Point Tracking (MPPT). The downlink on 437.150 MHz will be CW, 1200 bps AFSK or 9k6 GMSK telemetry.
The satellite has attracted the attention of the press. Read one Japanese newspaper story in Google English at http://tinyurl.com/Nikkan-OPUSAT-130815
A launch is planned on the JAXA H-2A-202 rocket in Spring 2014 into a 400 km circular 65 deg orbit along with the primary payload Global Precipitation Measurement (GPM) Dual-Frequency Precipitation Radar (DPR). There should be a number of other satellites carrying amateur radio payloads on the launch, including:
• STARS-2 – Kagawa University
• TeikyoSat-3 – Teikyo University
• ShindaiSat – Shinshu University
• INVADER – Tama Art University
• ITF-1 – University of Tsukuba
