About
The ST200 is a compact star tracker from AAC Hyperion designed for CubeSat and small satellite attitude determination. It captures images of the star field and uses pattern recognition algorithms to determine the satellite’s 3-axis attitude with high accuracy. The ST200 is suitable for Earth observation and precision pointing missions where magnetometer and sun sensor accuracy is insufficient.
