    ST200 Star Tracker

    The ST200 is one of the world’s smallest and lightest fully autonomous, low power star trackers, aimed at applications in pico- and nano-satellite platforms.

    The ST200 is also suitable for applications on larger satellite platforms. For these applications, additional interfaces and power supply ranges are available.
