PRECISE POSITIONING USING THE MODIFIED AMBIGUITY FUNCTION APPROACH WITH COMBINATION OF GPS AND GALILEO OBSERVAIONS

摘要

This paper analyses precise positioning using combined GPS and Galileo observations. Sixteen Galileo satellites were used during the tests, along with three days of data (4-6 January 2018). The Modified Ambiguity Function Approach (MAFA) method is used for data processing. The experiment presented in this paper was divided into two parts. In the first part, RTK positioning was performed, while in the second part, long-time static sessions were performed. The results obtained using GPS only and GPS+Galileo combination were compared. The results indicate that combined GPS and Galileo positioning has a clear advantage over single-system solutions and provides an accurate and reliable solution.
