Abstract
In this research, the position errors derived from Global Navigation Satellite System (GNSS) signals of two different brands of smart phones are assessed. To perform the experiment, two smartphones Samsung Galaxy Note 8 and Google Pixel 1 have been chosen. The main goal of this test is to compare the position accuracy of each phone. As different environments such as open-sky or partially blocked view affect the received satellite signal levels; therefore, we made the test by recording the GNSS signals in crowded city areas, where many buildings can be found, and open areas, where there are no obstructions. The raw data are processed using the recently available open-source software named Google Analysis Tools. The results show that the received GPS signal in the clear environment have lower errors and more accurate than in the city environment. It can be seen that Galaxy Note 8 has the ability to locate places better (less error values) than Google Pixel.
