Abstract : A lightweight, inexpensive suntracker for balloon applications is described. The entire tracking system including power supplies for a 12-hour flight weighs 3 pounds 14 ounces. The system has demonstrated in the laboratory a capability of pointing a 3 pound 2 ounce load at the sun within plus or minus 0.12 degrees. A very simple and reliable acquisition and tracking technique is employed which uses no vacuum tubes or transistors. (Author)
