DTU Star Tracker Enhancing Satellite Attitude Determination

A DTU star tracker is an optical sensor designed to detect and analyze star positions, allowing satellites to determine their orientation in space. By comparing captured star patterns with an onboard catalog, it provides real-time attitude data, which is critical for navigation and control.

How Does a DTU Star Tracker Work?

1. Star Detection: The sensor captures images of the night sky, identifying bright stars.
2. Pattern Recognition: The onboard processor matches star patterns with a reference catalog.
3. Attitude Calculation: Using advanced algorithms, the system determines the satellite’s orientation.
4. Data Transmission: The attitude information is sent to the satellite’s attitude control system for precise maneuvering.
