We are developing a bread board model for a microwave wireless power transmission (WPT) from a satellite in orbit to the ground. WPT using microwaves is one of the critical and important technologies toward a solar power satellite (SPS). We have carried out a conceptual design and proposed a space experiment using a scientific small satellite which has been developing by JAXA. The purposes of the...
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 ground. Microwave power transmission has...
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 dimensional direction by the pilot signal and the phase...
