A star sensor for Cubesat is an optical device used to determine a satellite’s orientation in space by recognizing star patterns. It is an essential tool in the satellite’s attitude determination and control system (ADCS).
Cubesats are small, power-limited platforms that require efficient, low-mass sensors. Star sensors deliver autonomous, precise, and reliable attitude data without ground support, making them ideal for high-accuracy applications.
A star sensor captures images of the sky and compares the star field to an onboard catalog. Based on the detected star patterns, it calculates the satellite’s orientation with arcsecond-level accuracy.
