GPS Signal Generation, Acquisition, and Tracking Simulation

In this article, we provide a detailed explanation of how to simulate GPS signal generation, acquisition, and tracking processes using MATLAB. Through these simulations, users can gain deeper insights into GPS system working principles and learn how to model these processes using MATLAB programming techniques. The implementation includes code for generating GPS signal waveforms with proper modulation schemes, acquisition algorithms using correlation techniques to detect satellite signals, and tracking loops employing phase-locked loops (PLLs) and delay-locked loops (DLLs) for maintaining signal lock. We provide complete source code to help readers understand the simulation implementation methodology, enabling them to experiment with modifications and improvements. Key MATLAB functions used in the simulation include signal processing tools for correlation calculations, communication system blocks for modulation/demodulation, and custom algorithms for navigation data processing. This resource aims to enhance understanding of both GPS systems and MATLAB-based simulation techniques, providing practical hands-on experience for technical professionals and researchers.
