The subject of this article is to answer the question regarding the possibility of using the Global Positioning System (GPS) in modern mobile phones and to examine the accuracy of position determination using the phones tested in the experiment. The following study contains a description and characteristics of the three tested phones: Nokia 6110 Navigator, Nokia E, and Samsung i550w. The structure and genesis of mobile telephony itself and the introduction of the GPS system into GSM phones are also outlined. The analysis of the accuracy of position determination using individual phones is based on a comparison of the obtained coordinates with reference coordinates obtained from a precise Topcon HiPer Pro geodetic receiver.May 1, 2000, was a breakthrough day in the history of the Global Positioning System. On this day, the so-called Selective Availability (SA) was turned off, which resulted in a more than tenfold increase in the accuracy of position determination for civilian users of the GPS system. The removal of SA had a huge impact on both the then-current and future users of the system. Thanks to (…)
