The Japan Aerospace Exploration Agency and the Institute for Unmanned Space Experiment Free Flyer are planning to conduct a microwave power transmission (MPT) ground experiment in fiscal year 2014. We will use an important MPT technology called beam steering control (BSC). The BSC technology accurately controls microwave beam pointing to a power receiving(More)
Solar Power Satellite (SPS) is an energy system which collects solar energy in space and transmits it to the ground. It has been believed as a promising infrastructure to resolve global environmental and energy problems for human beings. One of the most important technologies for the SPS is the wireless power transmission from the geostationary orbit to the(More)
We develop electrical functional models of the space solar power system (SSPS) for the system study and the practical demonstration of the end to end capability from space to the ground. The model generates electricity by the solar array and converts the DC power into microwaves with a frequency of 5.8 GHz. The microwave beam is controlled in one(More)
