“…Table 5 shows the global scientific research carried out over the last few years, during which the accuracy of static (stationary method) position determination in the group of smartphones and sport-recreational receivers was assessed. It is worth adding that there is much more research on the assessment of kinematic position determination accuracy [43–47], [31] than stationary described in this research.…”

Achieving single meter positioning accuracy by portable mobile devices still poses a major challenge to the satellite signal receivers constructors, despite gradual constellation completing process and the progress achieved in last decades. Nowadays popular smartphones are multifunctional devices that serve also as a personal navigation tool in navigation and sport activities using the global navigation satellite systems (GNSS) receivers installed. It would seem that introducing newer models to the global market would cause constant progress in the accuracies obtained, however, the study results do not confirm that. This study focused on Galaxy series smartphones of Samsung, one of the leading manufacturers worldwide, to examine its technological progress. The aim was to verify the thesis using statistical models and analyses to compare succeeding generations of smartphones on six devices from the series. The authors conducted two synchronous stationary measurement campaigns of 24 and 12 hours with one-second interval in obstacle-free environment which provided 70000+ and 30000+ statistical samples of position measurements. The reference values of true smartphones coordinates were determined by means of state-of-the-art precise surveying instruments and geodetic calculations. The results indicate that two newest generations of the Galaxy series included in the research, namely S6 and S7, obtained lower accuracies than their predecessors. Against the backdrop of lack of public availability of smartphones technical parameters, the conducted research results are relevant especially to smartphones positioning service users community.

Background: Satellite navigation systems have been used in professional navigation and geodesy for many years. The past decade has been a time of extending their application to devices also accessible to non-professional users. Sports and recreation is one of the major new areas in which satellite receivers are used. Since device manufacturers do not inform precisely (or at all) about the level of the positioning accuracy provided by such devices, it is necessary to propose a method of its assessment. This paper presents selected aspects of testing receivers in dynamic measurements to determine their accuracy based on international recommendations and standards applicable to validation of professional navigation GNSS devices. It also presents a number of examples of practical tests, based on many years of the authors' experience, to which comments were added.
