MATLAB Implementation for GPS Satellite Simulation with 3D Animation

This MATLAB-based GPS satellite simulation excels in 3D animation and GUI implementation. The simulation models satellite orbital trajectories using Keplerian elements and coordinate transformation algorithms, implements signal transmission through PRN code generation and modulation techniques, and demonstrates receiver operation via correlation-based signal acquisition and tracking loops. Parameter adjustment capabilities allow for scenario-specific simulations, including different orbital configurations and atmospheric conditions, yielding realistic and accurate results. MATLAB's comprehensive toolbox (particularly Aerospace and Communications Toolboxes) provides essential functions like satelliteScenario for trajectory visualization and comm.GPSNavigationData for signal generation, streamlining the simulation workflow. Key implementation aspects include: - Orbital mechanics calculations using SGP4 propagation algorithms - 3D visualization with MATLAB's handle graphics and animation objects - GUI components built with App Designer for interactive parameter control - Signal processing chains incorporating Doppler shift compensation and pseudo-range calculations This approach provides an effective and reliable methodology for understanding GPS technology applications through customizable simulation environments.
