Abstract
Abstract Achieving high accuracy by GNSS (Global Navigation Satellite System) positioning is in demand in many industries, including transport, where ensuring the positioning of moving vehicles with an accuracy of 1-3 meters is an essential condition in the development of intelligent systems for monitoring and optimization of road traffic. In this case, the task should be solved in such a way as to be accessible to a wide range of users, and thus be simple and cheap. In this paper, in order to achieve accurate GNSS positioning of a moving car is considered the use of a smartphone, as the most popular navigation device of a typical user, raw data of which is processed by differential correction using the Automated Control System for Reference GNSS Station Network. Positions obtained by smartphone is compared with data obtained by the u-blox receiver. The experiment is conducted in an urban area typical for Kazakhstan. It is shown that using a smartphone as a navigation aid with a further differential correction from one reference station allows positioning with accuracies at least of 1.4 meters.
