Simulation of Carrier Tracking Loop in GPS Tracking Module

This article explores a simulation program for the carrier tracking loop in GPS tracking modules. The program implements detailed signal processing algorithms to model the complete carrier tracking process, helping researchers better understand the module's operational principles. Our simulation incorporates phase-locked loop (PLL) algorithms, Costas loop designs, and Doppler shift compensation models to replicate real-world GPS signal conditions. The program enables observation and analysis of various dynamic factors during carrier tracking, including signal strength variations, interference patterns, multipath effects, and phase noise characteristics - all critical elements affecting GPS module performance. Through this comprehensive simulation approach utilizing MATLAB/Simulink implementations with configurable parameters for loop bandwidth, integration time, and noise thresholds, users can gain deeper insights into GPS tracking mechanisms, providing valuable support for both research studies and practical engineering applications.
