METHOD AND APPARATUS FOR CONTROLLING A SOLAR WING OF A SATELLITE USING A SUN SENSOR This invention discloses a method for maintaining a desirable orientation of the solar wings of an orbiting satellite (103 relative to the sun. A dual array of sun sensors (26,28) is positioned on a body (12) of the satellite (10) in order to get a measurement of the position of the sun relative to the body (12) once per every orbit of the satellite (10). In addition, an estimate of the position of the solar wings (16, 17) relative to the body (12) of the satellite (10) is attained. The sun to-body angle is then subtracted from the body-to-wing angle to drive an error signal which is applied to a wing driver mechanism in order to maintain the solar wings (16,17) of the satellite (10) in a proper orientation relative to the sun.
