AbstractSolar Power Satellite (SPS) which has been received a considerable public concern by the efficient utilization of the sunlight remains many issues which should be studied. Construction of a large scale solar panel and a transmitting antenna is one of the important subject toward SPS. I carried out the experimental study on the construction and flatness maintaining a large-sized antenna for the SPS. The wireless microwave power transmission method is used for the SPS system. The panel should be distorted by the heat cycle on the orbit, and the power transmission efficiency degradation will be resulted. Therefore, the high reliable construction of the antenna panel and the flatness maintaining control are required in order to achieve high efficiency power transmission. In this paper, we propose a new construction method of the large-scale panel structure in the orbit and the flatness control by a smart actuator system. It was confirmed that our smart actuator system has a angular control function with sufficient accuracy. I compared the smart actuator with the conventional actuators and summarized the advantages of our actuator using Shape-Memory Alloy (SMA). If SMA is used at high temperature, it will deteriorate. Therefore, the temperature in the inside of a vacuum was measured. I proposed a new constructing method of the large-scale panel structure method in the orbit.
