About
The nanoST (Star Tracker for Nano Satellites) is an accurate attitude determination device from Solar MEMS for nanosatellites. It captures images of a star field using an internal CMOS sensor and identifies stars and constellations to determine satellite pointing and attitude with high accuracy. The nanoST is a true plug-and-play system requiring no additional electronics or external support modules. Beyond space, it is also suitable for aeronautical applications, providing drones and unmanned vehicles with high-precision orientation and positioning in GNSS-denied environments. Its compact design, high reliability and straightforward integration make it ideal for challenging aerospace environments. Available in Engineering Model (EM) and Flight Model (FM).
