MATLAB Implementation of Coherent Integration Algorithm for GPS Signal Acquisition Process
GPS signal acquisition source code for MATLAB simulation, featuring correlation-based signal detection and frequency search algorithms
This comprehensive GPS software receiver solution includes complete acquisition and tracking algorithms with detailed code implementation for satellite signal processing, suitable for researchers and developers working with Global Navigation Satellite Systems.
Application Context: GPS technology is extensively utilized across daily life, scientific research, and industrial applications. This program performs GPS signal acquisition and satellite searching by determining visible satellite PRN numbers, Doppler frequency shifts, and initial code phases. The results obtained can be further utilized for signal tracking and navigation solution computation. Key Technologies: ca_repeat.m generates sampled sequences of specified C/A codes, CAENCODE.m produces C/A code sequences, findmax.m identifies peak values in correlation results, and GPSAcq.m serves as the main acquisition function. The program allows customization of GPS signal parameters including frequency points, intermediate frequency, and sampling rate during initialization. The code package includes real GPS datasets for practical testing and validation.
