Abstract : A star sensor onboard a satellite determines the orientation of the satellite in space. It provides very accurate orientation information compared to a sun-sensor or a magnetometer, but star sensors are too expensive and some times bulky for use in small satellite missions. In this poster, we will discuss the development of a low-cost star sensor using Raspberry Pi and COTS components for small satellite missions. Also, we will describe the geometric voting algorithm implemented in our star sensor. Our star sensor will be launched on a PSLV stage 4 platform to a low Earth orbit(LEO), where its in-flight performance will be measured.
