description: The subject of the graduate qualification work is âModeling and implementation of the GNSS signal generation algorithms in FPGA for the local navigation systemâ. This work is devoted to the study of existing local navigation and positioning systems based on pseudolites using GNSS signals or similar to them, as well as the implementation of algorithms for generating GPS signals in FPGA. The first section describes the existing local navigation systems and navigation systems based on pseudolites. Also, in this section, the basics of generating GPS signals and generating of harmonic oscillations in digital devices are presented. The second section is dedicated to modeling the GPS transmitter and receiver in MATLAB. The third section presents the implementation of GPS signal generation algorithms in FPGA. The aim of the work is to implement GPS signal generation algorithms in FPGA for usage as a pseudolite of a local navigation system. In the course of the work the simulation of the transmitter and receiver of the GPS signal was carried out. Based on the simulation, a study was conducted of the dependence of the standard deviation of coordinates determined by the receiver, depending on the DAC resolution. Also, software for FPGA that implements GPS signal generation algorithms was written. A simulation based on this software was conducted in the Vivado environment. The results could be used as the basics for developing of local navigation system based on GNSS signals or similar.
