        abstract = {This paper explores the design and implementation of a software-defined GPS receiver, leveraging advancements in software-defined radio (SDR) technology. Traditional GPS receivers rely on heterodyne architectures with limited flexibility, whereas SDR-based receivers offer reconfigurability through digital signal processing (DSP). By employing direct RF digitization and band-pass sampling, these receivers can adapt to different signal processing tasks. However, challenges such as signal bandwidth constraints and ADC dynamic range requirements must be addressed. A practical solution involves incorporating a programmable intermediate frequency (IF) stage and partial band digitization. The SDR approach provides advantages in flexibility, reduced hardware costs, and improved testing efficiency. This research highlights the potential of SDR-based GPS receivers in modern navigation systems and discusses key design considerations for optimizing performance.},
