About
The Twinkle Star Tracker is a compact and easily interfaced star tracker designed for CubeSats and larger satellites. It offers arc second range pointing accuracy, crucial for precise attitude determination in space missions. The device incorporates custom algorithms that are specifically optimized for high accuracy, robustness against various operational conditions, and low computational cost, making it efficient for resource-constrained satellite platforms. Its small size allows for flexible integration, and multiple units can be mounted at different angles to further enhance overall pointing accuracy. This design approach provides redundancy and improved performance for demanding satellite applications.
