Lecture
This lecture covers the fundamentals of GPS signals processing, including sources of error, ephemeris, satellite health, and the process of calculating user positions using GPS receivers. It explains the acquisition time of GPS signals, the correction of distances due to the ionosphere and troposphere, and the parameters involved in GPS messages. Additionally, it delves into the modeling of satellite clock errors, receiver position unknowns, atmospheric errors, and the resolution matrix of parameter cofactors.
