GPS Signal Structure: Evolution and Applications

This lecture covers the evolution and structure of GPS signals, including the use of carrier waves, modulated codes, and positioning accuracy. It delves into the concept of satellite tracking, the GPS coordinate system, and the principles of absolute and relative localization. Additionally, it explores the GPS time reference system, satellite ephemeris, and the global terrestrial reference system. The instructor provides insights into the signal structure, message content, and the role of GPS in determining precise locations on Earth.
