PhD Seminar Series: “Lost in Space: How to Navigate around the Moon and Beyond?”

This seminar will cover on-going research efforts on autonomous optical navigation for deep- space missions. Applications of interest include trajectories beyond Geostationary Earth Orbit, lunar transfers, lunar orbits, and missions to asteroids or comets. We explore the potential of techniques such as edge detection, centroiding, neural network-based feature detection (for lunar crater and Earth coastline detection), pattern recognition, etc. An overview of our simulation framework is provided, including image generation, image processing, characterization and modeling of measurement errors, filtering, uncertainty quantification, and validation through hardware-in-the-loop experiments. Autonomous optical navigation can enable lower cost, more flexible, independent, resilient, and sustainable space exploration, and its promise, technical challenges, expected performance, and limitations are discussed in this talk.
