Explore spacecraft dynamics in this comprehensive lecture covering satellite reference frames, viewing geometry, and mission analysis fundamentals. Delve into essential reference frames used in spacecraft dynamics, including Earth-centered inertial (ECI), Earth-centered Earth-fixed (ECEF), orbital frames, and spacecraft body-fixed frames. Learn crucial mission analysis concepts such as sub-satellite point, instantaneous access area, swath width, and ground track. Gain insights into satellite viewing geometry and its applications in space missions. Discover the interconnections between various coordinate systems and their importance in spacecraft operations. Enhance your understanding of space vehicle dynamics through detailed explanations, visual aids, and practical examples provided by Dr. Shane Ross, a professor of Aerospace and Ocean Engineering at Virginia Tech.
