About
The Twinkle Star Tracker is arcsec’s most compact star tracker, offering arc second range pointing accuracy to CubeSats and large satellites. Its extremely small form factor allows several units to be mounted at different angles on the same satellite to improve overall attitude accuracy. The custom algorithms are optimized for accuracy, robustness, and low computational cost. With a cross-boresight accuracy of 3″ (1σ) and around-boresight accuracy of 30″ (1σ), it is easy to interface and radiation-tolerant for space applications. It communicates via RS485 and weighs only 35 g.
