Development status of the beam steering control subsystem for the microwave power transmission ground experiment

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 subsystem. We researched the BSC method and the beam pointing accuracy. This paper describes the functions and specifications of BSC, and analysis results of beam pointing accuracy in the MPT ground experiment.
