About
The MicroST is a high-precision attitude determination star tracker from Solar MEMS designed for microsatellite missions. It captures images of a star field using an internal CMOS sensor and identifies stars and constellations to determine satellite pointing with very high accuracy. Like all Solar MEMS star trackers, it is a plug-and-play system requiring no additional electronics. The modular architecture allows standalone and multi-camera configurations, making MicroST adaptable for a wide range of microsatellite missions in LEO, MEO and GEO. Its compact design, high refresh rate and autonomous operation enable precise Guidance, Navigation and Control (GNC) capabilities. Available as Engineering Model (EM) and Flight Model (FM), with RS422, CAN bus or Ethernet communications available on request.
