A HIGH ACCURACY FINE SUN SENSOR.

Abstract

Design and constructional details are given for a sensor suitable for fine guidance of sun pointing space vehicles. Factors affecting the accuracy and stability of the sensor are discussed and optimum values for certain critical parameters suggested for Skylark and satellite applications. Bias error measurement methods are described and it is concluded that, because of atmospheric turbulence, results using the real sun are unreliable; an alternative method using a solar simulator is presented which has given results repeatable to about 2 arc sec.
