Selected aspects of testing the positioning accuracy of GNSS receivers used in sports and recreation by dynamic measurements

Abstract

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.
