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.
With an accuracy of 30 arcseconds and its extremely small size the ST200 can be used in practically every platform that requires attitude determination.
The ST200 is a co-development with our partner Berlin Space Technologies.
- Accuracy: 30 arcseconds (3-sigma)
- Update rate: 5 Hz
- TTL UART interface
- Power consumption: 650 mW (nominal)
- Mass: 42 g
- Supply voltage: 3.65V (3.6 – 5.0V)
- Various suitable baffle options are available on demand
The ST200 Star Trackers have been flying on 14 missions ever since 2015.
The TRL of the ST200 is at 9.
Our Star Trackers of the ST200 series are compatible with two standard baffles with either 45 or 30 degree sun exclusion angle (half angle). Other exclusion angles are available on request.
As a default our ST200 comes with a TTL UART interface. An RS422 interface is also available.
Our Engineering models, including the baffles, undergo collimation in air, whereas flight models are tested in vacuum. Both models undergo workmanship testing at different levels.
We offer acceptance testing of the Flight Model as well as qualification testing.
