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, high-confidence orientation knowledge, and fit within the broader spacecraft architecture.
Mission fit
Built for spacecraft that need dependable orientation awareness.
Star trackers matter when payload performance depends on knowing exactly where the spacecraft is pointed. They sit within a broader spacecraft hardware portfolio.
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, and integration alongside the rest of the avionics, control architecture, and wider platform decisions.
What to bring into the conversation
- Mission profileOrbit, payload constraints, and pointing expectations that define how demanding the attitude-determination requirement really is.
- Control architectureHow the tracker needs to fit alongside the broader ADCS stack, integration approach, and spacecraft architecture rather than as an isolated component choice.
- Program stageWhether the team is in early architecture review, supplier narrowing, or active technical evaluation.
Key considerations
What usually drives the decision.
Key factors in star tracker selection.
Selection depends on the full stack.
The right star tracker depends on how it participates in the spacecraft control architecture, avionics approach, mission operating envelope, and the wider platform design around it.
