This paper describes a hardware approach of one part of GPS receiver — the acquisition and tracking of GPS code and the frequency tracking. Method used for acquisition and tracking code is Fast Fourier Transform, which provides fast acquisition at first step. Costas loop is used for frequency tracking and demodulating GPS signal. The design is implemented in FPGA with support of mega-core functions.
