ABSTRACT:
A wind resistant, two axis tracker is used to direct a solar reflector, heliostat, or dish antenna. An elevation drive ring is supported in a vertical orientation by dolly wheels rotatably attached to a base. The reflector is attached at two points along the circumference of the elevation drive ring. In the prreferred embodiment, a reflector having a diameter slightly less than the inside diameter of the elevation drive ring is mounted to the elevation drive ring. A number of support members, such as cables, extend from the elevation drive ring to the periphery of the reflector. Azimuth adjustment is either provided by incorporating a horizontal turntable or drive ring as part of the base, or by pivoting the reflector within the elevation drive ring by adjusting the respective lengths of the support cables extending laterally from the elevation drive ring to the periphery of the reflector.
