Attitude knowledge shapes payload value.
For pointing-sensitive missions, star tracker performance is not just an ADCS detail. It affects whether the payload can deliver the required output reliably.
Space Inventor product
Star Trackers
Precision attitude-determination hardware for spacecraft that depend on stable pointing and reliable orientation knowledge.
Mission requirements
Built for spacecraft that need dependable orientation awareness.
Use this page when pointing accuracy, calibration stability, payload performance, and spacecraft integration drive tracker selection.
Where they matter most
Earth observation, remote sensing, and other payload-driven missions where pointing error directly affects image quality, target acquisition, or overall mission confidence.
What teams are evaluating
How the tracker supports precise attitude knowledge, calibration stability, avionics, and control architecture.
What to share
- Mission profileOrbit, payload constraints, and pointing expectations that define the attitude-determination requirement.
- Control architectureHow the tracker works with the ADCS stack, integration approach, and spacecraft architecture.
- Program stageWhether the team is in architecture review, supplier narrowing, or active evaluation.
Key considerations
What usually drives the decision.
Key factors in star tracker selection.
Selection depends on the spacecraft system.
Star tracker selection depends on the control architecture, avionics approach, mission operating envelope, and platform design.
