Source Code for a Satellite Navigation Book

The book provides detailed satellite navigation implementations including robust source code for key functionalities like weighted least-squares position solving, Keplerian orbit propagation for ephemeris calculation, and integer ambiguity resolution techniques such as LAMBDA method. These modular code segments demonstrate practical GNSS algorithm implementation with clear variable naming and mathematical commenting. Beginners can trace through commented examples showing step-by-step coordinate transformation, satellite clock error correction, and atmospheric delay modeling. The repository includes working simulations for pseudorange measurement generation and carrier-phase processing loops, serving as both educational templates and research foundations. Special gratitude to the author for providing this structured resource that significantly lowers the entry barrier for satellite navigation algorithm development and promotes reproducible research in positioning technology.
