Abstract
A method is provided to track the sun. An omnidirectional sensor is used for acquiring sun's position. The sensor can track sun's position in an omnidirectional way. A controller is also provided to control the tracking. When the sun shines strongly, the sensor is controlled to track the sun's position. When the sun does not shine strongly, the tracking is stopped. Thus, the cost for tracking the sun's position is reduced and accuracy of the tracking is enhanced.
