Spoofing detection test of GPS signal interference mitigation equipment

Global Navigation Satellite System(GNSS) is vulnerable against the interference signal because the navigation signal is very weak on the ground. If the interference signal is induced on a GNSS receiver, the GNSS receiver will malfunction by the interference signal. In the point of national infrastructure, the protection of the GNSS signal becomes more important. For preventing the interference effects, Electronics and Telecommunications Research Institute(ETRI) developed GPS signal interference mitigation equipment. In this paper, we introduce the process and result of spoofing detection test. The spoofing detection function is the part of GPS signal interference mitigation equipment.
