Contributor Theuwissen, A. (promotor) Faculty Electrical Engineering, Mathematics and Computer Science Department Microelectronics & Computer Engineering Date 2012-07-02 Abstract A digital sun sensor is superior to an analog sun sensor in aspects of resolution, albedo immunity, and integration. The proposed Micro-Digital Sun Sensor (µDSS) is an autonomous digital sun sensor which is implemented by means of a CMOS image sensor, which is named APS+. The µDSS is designed specifically for micro-satellite application which addresses for low power and high accuracy. The APS+ significantly reduces the power consumption by a profiling method and obtains low noise by a quadruple sampling method. Measurement results show that the µDSS achieves an accuracy of 0.01º with 21mW@10fps, which is 10 times less than the state of the art.
