Sun Sensor is a commonly used sensor in satellites for attitude determination. This paper discusses the design and development of 2-axis digital sun sensor (DSS) using commercial-off-theshelf (COTS) components. The CMOS linear array based simple design of DSS, having a field of view of ±45°, has been implemented with a Sun angle determination accuracy of 0.5°. Three such sensors mounted appropriately on satellite’s platform can determine the sun angle in normal conditions. The design offers a low-cost and power efficient solution for micro-satellites.
