摘要:This article analyses measuring errors caused by various factors, as well as technology of GPS. Incorrect data occur as of errors in clocks, disturbances while signal travels through atmosphere, relativistic causes, geometry and orbits of satellites and reflection of signals. Solutions of these problems and the elimination methods are mentioned. Based on the analyzed data, the new process of utilization is proposed, applied in transportation timetable design, with successful implementation of the error minimization.
