Abstract
In this paper, code and carrier tracking error which resulted from spoofing signal was analyzed by simulation. For a start, the types of spoofing signals and methods were classified. For the simulation, search spoofing method is assumed because a perfect position and velocity are not generally informed to spoofing device. In most cases, the tracking error is increased but a complete deception does not happen because of the inherent anti-spoofing characteristics of the GPS signal.
