Now-a-days, advanced mobile devices can obtain current position with the help of positioning data systems such as GPS, GLONASS, Galileo, and so on. However, positioning data sets usually have erroneous data for various reasons, mainly due to the environmental issues as well as inherent systematical issues. While doing research related to positioning data sets, authors experienced quite a large number of erroneous positioning data using Apple iPhone or Samsung Galaxy devices, and thus need to filter evident errors. In this paper, the authors will suggest relatively simple, but efficient filtering method based on statistical approach.
