Abstract

This bachelor's thesis deals with the design and construction of a base station for the GNSS RTK method, providing real-time correction data via the NTRIP protocol and a local network through an open port. The theoretical part describes the principles of navigation satellite systems, methods of transmitting corrections, and an analysis of error sources. The practical part documents the realization of the station, the selection and implementation of hardware components, the RTKLIB software solution (str2str), and the process of determining the station's position using the PPP method. The final part of the thesis is devoted to real measured data. The power consumption of the base station, the accuracy of its position determination using the PPP method, and the error effects occurring during signal transmission were analysed. The functionality of the system was verified in the field, where the device operated as a fully autonomous off-grid system.
