ST200 CAD MODEL
CubeSat Star Tracker
Our ST200 CubeSat star tracker offers attitude determination in an incredibly small package. The ST200, developed by AAC Hyperion, 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 also suitable for applications on CubeSats as well as larger satellite platforms. For these applications, additional interfaces and power supply ranges are available. Optionally AAC Clyde Space offers standard size and mission-specific baffles.
The ST200 was co-developed by AAC Hyperion and Berlin Space Technologies.
Accuracy
With an accuracy of 30 arcseconds (3-sigma) and its extremely small size the ST200 can be used in practically every platform that required attitude determination.
Design
With its plug-and-play design and various baffle options available on demand the ST200 is the perfect star tracker to seamlessly integrate with AAC Hyperion’s line of integrated attitude determination and control systems.
Why the ST200?
- Accuracy: 30 arcseconds (3-sigma)
- Update rate: 5 Hz
- TTL UART or RS422 interface
- Power consumption: 650 mW (nominal)
- Supply voltage: 3.65V (3.6 – 5.0V)
- Various suitable baffle options are available on demand
