GPS doesn’t work the way most people assume in space—so spacecraft rely on something ancient and incredibly precise: the stars. In this video, we break down how star trackers provide attitude knowledge so satellites can point antennas, cameras, and solar arrays accurately.
You’ll learn what a star tracker “sees,” how onboard software matches star patterns, why calibration matters, and how satellites combine star tracker data with gyros and reaction wheels for stable control. We also discuss why these sensors can cost hundreds of thousands and what happens when they’re blinded by the Sun or Earth glare.
Great for anyone into satellite attitude determination, spacecraft navigation, space sensors, and real-world aerospace systems explained simply.
