The primary challenges faced during development of the T3 Star Tracker is to meet the very low physical envelope and power budget placing it as a strong candidate in the small satellite market.
The T3 Star Tracker will fit into an envelope of 60x60x100 mm while maintaining a total power consumption of less than 1W.
The T3 Star Tracker can provide attitude estimates at 5 Hz with an accuracy exceeding 2 arcseconds even under slew rates up to 1.5 deg/s.
Decomposing T3, it consists of a focal plane (with the sensor) and a computer in a single housing, with optics and baffle mounted on top.
The project consists of the following overall phases:
- Trade-Off & Consolidation Phase
- Design Phase
- Manufacturing & Test Phase
With phase transitions governed by the following reviews:
- Mid-Term Review
- Preliminary Design Review
- Final Review
Work is currently taking place in the Trade-Off & Consolidation Phase approaching the Mid-Term Review.
