The purpose of the work is to study and develop a synchronization algorithm using the NTP protocol. As a result of the study, various algorithms for connecting intrasystem time were considered, with an emphasis on the NTP (Network Time Protocol) connection protocol. The features of the operation of this protocol, its effectiveness and influence on the accuracy of the position of satellite navigation are considered. As part of the general study, an analysis is made of the use of NTP to search for time in satellite navigation sources and the possibility of assessing the quality of search in conditions of insufficient search for intrasystem time. A detection algorithm has been created that has a higher frequency of occurrence. The application and scope of this algorithm have been studied. Open educational resources and programs for searching and analyzing information were used. The research method includes the use of NTP analysis to determine the time in satellite navigation, the frequent possibilities of quality assessment in conditions of insufficient determination of intrasystem time, as well as the description of the algorithm code in Qt to evaluate measurements and evaluate its effectiveness.
