A novel micro Digital Sun Sensor (μDSS) is under development in the frame of a micro systems technology (MST) development program (Microned) from the Dutch ministry of economic affairs. Use of available micro system technologies allows TNO TPD to developing a fully autonomous and wireless sun sensor that is small enough to be flown on a microsatellite [4]. Using a dedicated solarcell for power supply and a wireless link for data communication to an optimised masked APS ASIC, allows building a truly autonomous system in a package. Due to a careful trade-off between mass, complexity, flexibility and performance, a sensor can be devised which is small enough to be flown on even the smallest satellite without compromising the measurement performance. Key performance figures for the sensor are: FOV > 120°, accuracy < 0.1°, mass < 30g. Due to the high level of integration and the use of sub micron CMOS technology, the sensor is expected to exhibit a large reliability and radiation tolerance, and foremost a low recurring cost.
