ST400 datasheet Product enquiry ST400 CAD MODEL

SmallSat Star Tracker

Powerful attitude determination for small satellites. The ST400-T star tracker, developed by AAC Hyperion,  is aimed at microsatellite systems. With increased attitude determination accuracy and improved radiation tolerance compared to its little brother, the ST200, it enables more demanding missions.

The ST400-T is a standalone, low mass, low power star tracker, which renders attitude determination capability to small satellites. The ST400-T is an improved version of the smaller ST200 star tracker, which is aimed at applications in pico- and nanosatellite platforms. Qualified for man-rated missions it features increased attitude determination accuracy and increased radiation tolerance.

The ST400-T is prepared to accept very narrow sun-exclusion angle baffles, which we can can supply on demand. The dedicated RS422/RS485 interface allows networking multiple ST400-T’s, which combined with narrow sun-exclusion angle baffles means that even for the most complex satellite and orbit geometries, there will always be a configuration that works. The ST400-T is a co-development between AAC Hyperion and Berlin Space Technologies.

  • Accuracy: 10 arcseconds (3-sigma)
  • Update rate: 5 Hz
  • RS422/RS485 bidirectional interface
  • Power consumption: 700 mW (nominal)
  • Supply voltage: 4.5V – 15.5V
  • Various suitable baffle options are available on demand
