The aim of this article is to discuss the possibility of exploiting receivers with GPS satellite navigation function as a source of evidence useful in road accident reconstruction. A number of navigation receivers available record the so-called track, which is described by geographical coordinates of the vehicle’s position and velocity at given intervals of time. A number models of such equipment have been investigated, including their data recording mode and the method of saving them. Caution is necessary when interpreting vehicle movement parameters read from a file containing route track, and interpretation errors are highlighted. APRS and other ways of track recording on Internet servers are briefly outlined.
