The Twinkle Star Tracker offers arc second range pointing accuracy to CubeSats. The custom algorithms are optimized for accuracy, robustness and low computational cost. The star tracker is compact and easy to interface in CubeSats and large satellites. Due to its small size, several can be mounted under different angles.

Key features:

  • Tracks stars up to magnitude 6
  • On-board calibration algorithm
  • Lost-in-space availability: >99% of the night sky
  • Autonomously detects and corrects for outlier stars
