Low cost attitude estimation system. Performance evaluation on an airbearing based testbed

In this work, a low-cost attitude navigation system for spacecrafts is presented. The system fuses measurements from a three axis MEMS gyroscope and a CCD camera that identifies a known pattern of points (which emulate the stars). The system has been implemented on an ARM Cortex-A8 processor, running a GNU/Linux operating system. The developed attitude system was tested on an air-bearing testbed as experimental validation.
