Japan Space Systems (J-spacesystems), formerly known as Institute for Unmanned Space Experiment Free Flyer (USEF), has been studying Space Solar Power System (SSPS), as future electricity alternative energy source since 1990s. From 2009, J-spacesystems started new research and development project of the Microwave Power Transmission ground test under a support of Ministry of Economy, Trade and Industry(METI). This project includes the study for high efficient and thin structured phased array antenna, and the study to realize high efficient rectenna element.
This WPT ground test is intended to be a precursor of next on-orbit demonstration. In this paper, status of this project is introduced. |
