GPS MATLAB Example Programs with Signal Data Implementation

This repository presents comprehensive MATLAB implementations for GPS signal processing and analysis. The examples include detailed telegram data parsing routines that demonstrate practical approaches to GPS data interpretation. Key implementations feature satellite ephemeris decoding algorithms, pseudorange calculations using both C/A and P codes, and carrier phase measurement techniques. The codebase contains functions for: 1) Navigation message extraction from raw GPS signals, 2) Satellite position computation using Keplerian orbital parameters, 3) Receiver position determination through least-squares estimation methods, and 4) Signal-to-noise ratio analysis for tracking performance evaluation. Each module includes error handling for data integrity checks and supports both L1 and L2 frequency band processing. These practical examples serve as valuable reference implementations for developing GPS-enabled applications, academic research in satellite navigation, and signal processing algorithm validation.
