Data Synchronization: Bit and Preamble

This lecture covers the process of bit synchronization after carrier and code tracking loops, including the conversion of samples to data bits. It also explains the location of an 8-bit preamble in GPS telemetry data, used for subframe identification. The lecture further delves into the extraction of navigation data from subframes, focusing on parity checks and encoding equations. Additionally, it discusses the extraction of the time of transmission from GPS signals, addressing pseudo-distance ambiguity and the role of the Hand-over-word. The lecture concludes with the pseudorange equation, detailing the calculation of user pseudorange and the impact of clock corrections.
