Nanostar Lacquer ST-1
A device used to measure the line-of-sight vector to a celestial body that can be seen by a sensor. These sensors keep a map of a particular segment of the universe in memory and compare this map to the constellations visible through the sensor FOV. If the comparison is successful, the satellite attitude is defined by roll, pitch, and yaw. The flight-proven Startracker ST-1 features an SoC system circuit and an optimized design of star catalog and chart recognition processing algorithms. One of the smallest star sensors on the market, the Star Tracker ST-1 has achieved observation accuracy of 10 inches (3 \ sigma) and dynamic performance of 1.5 ° / s, making it currently the most cost-effective start tracker.
