dc.description.abstract The focus of the document is the development and use of an algorithm that controls a heliostat, and the high level design of that heliostat. The heliostat is only controlled by the algorithm and had a specified accuracy requirement equal to or better than 0.5 degrees. The algorithm uses the elevation and azimuth angle of sun calculated to an accuracy of 0.0003 degrees as input. The algorithm positions the heliostat to ensure a continuous reflection of sunlight into a predetermined direction for the purpose of indoor illumination. The position of the sunlight reflected into the predetermined direction is marked on a vertical grid-board placed orthogonal to the intended reflection direction. Ideally the sunlight positions marked throughout the day will all be in one location. The reflected sunlight deviated from the intended direction by only 0.28 degrees. en_US
