Fundamentals of Vision Based Navigation

In this video, Dr. John Christian, an aerospace engineer and assistant professor at West Virginia University, dives into the fascinating world of Vision-Based Navigation (VBN). Learn how spacecraft use optical data, including images, to navigate through space, whether they're approaching planets, moons, asteroids, or other spacecraft. This webinar, part of the NASA Engineering and Safety Center (NESC) Guidance, Navigation, and Control (GNC) series, provides a comprehensive overview of the theory, applications, and challenges of VBN. 🔹 What You'll Learn: The history of vision-based navigation, from the Gemini program to modern missions like NASA's Space Launch System (SLS). How spacecraft capture and process images to extract useful navigation data. The difference between cooperative and non-cooperative objects in navigation. Techniques like star-horizon measurements, centroid and apparent diameter, and landmark tracking. How pose estimation and filtering are used to determine a spacecraft's position and orientation. Real-world examples from missions like Apollo, Voyager, and the International Space Station (ISS). 🔹 Key Takeaways: Vision-based navigation simplifies complex navigation tasks by using optical data. Cooperative systems (like reflectors or markers) make navigation easier, while non-cooperative systems (like asteroids) require more advanced techniques. Modern missions rely on both passive (cameras) and active (lasers) sensors for navigation. The future of space exploration will increasingly depend on autonomous vision-based navigation systems. 🔹 Who Should Watch? Aerospace engineers, space enthusiasts, and students.
