Theoretical principles of high-precision determination of coordinates in real time on the basis of satellite radio navigation systems

Objective: to create a model of high-precision real-time coordinate determinations based on global navigation satellite systems (GNSS) using the model of quality control, integrity and continuity of the DQI, information technology, wireless communication and the international NTRIP format.

Main results of the work:

• analysis, classification and justification of differential methods related to the spatial and temporal correlation of the main sources of navigation determination errors were carried out;
• a model for quality control, integrity and continuity of differential correction information (DCI) was developed and methods for assessing the quality criteria of DCI were determined;
• algorithmic and software for real-time correction of coordinate-time high-precision determinations were developed;
• a laboratory model of high-precision real-time coordinate determinations based on GNSS using information technology, wireless communication and the international NTRIP format was created;
• experimental studies of the basic algorithms of the system on the laboratory model in real conditions.
