Objectives
The objectives of the project are to develop a very compact star tracker targeting the increasing market for small satellites.
Benefits
The T3 Star Tracker will fit into an envelope of 60x60x100 mm while maintaining a total power consumption of less than 1W.
Features
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.
Challenges
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.
System Architecture
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.
Plan
The project consists of the following overall phases:
1. Trade-Off & Consolidation Phase
2. Design Phase
3. Manufacturing & Test Phase
With phase transitions governed by the following reviews:
1. Mid-Term Review
2. Preliminary Design Review
3. Final Review
Current Status
Completed.
