GPS Systems Literature: Inaccuracy Factors And Effective Solutions

摘要

Today, Global Positioning System (GPS) is widely used in almost every aspect of our daily life. Commonly,users utilize the technology to track the position of a vehicle or an object of interest. They also use it tosafely navigate to the destination of their choice. As a result, there are countless number of GPS basedtracking application that has been developed. But, a main recurring issue that exists among theseapplications are the inaccuracy of the tracking faced by users and this issue has become a rising concern.Most existing research have examined the effects that the inaccuracy of GPS have on users while othersidentified suitable methods to improve the accuracy of GPS based on one or two factors. The objective ofthis survey paper is to identify the common factors that affects the accuracy of GPS and identify an effectivemethod which could mitigate or overcome most of those factors. As part of our research, we conducted athorough examination of the existing factors for GPS inaccuracies. According to an initial survey that wehave collected, most of the respondents has faced some form of GPS inaccuracy. Among the common issuesfaced are inaccurate object tracking and disconnection of GPS signal while using an application. As such,most of the respondents agree that it is necessary to improve the accuracy of GPS. This leads to anotherobjective of this paper, which is to examine and evaluate existing methods as well as to identify the mosteffective method that could improve the accuracy of GPS.
