Focusing on the functional software library of GPS/Galileo, this reference provides original source code for various functions, models, algorithms, and tools. It is based on the author's textbook, "GPS - Theory, Algorithms and Applications," and includes software from the KSGsoft and MFGsoft programs developed at GFZ in Potsdam. Verified through real GPS data applications, the library encompasses physical and disturbance models, mathematical methods, adjustment and filtering algorithms, and various tools for comprehensive GPS data processing.
