In this paper, the meaconing effects on GPS receiver are analyzed by simulation according to the power and the time delay of meaconing signal. Meaconing is the reception, delay and rebroadcast of GPS signals to confuse a receiver. The effects of meaconing is more menacing than jamming because it can mislead the receiver to track wrong signal with less power than jamming. Meaconing is easy to implement and it can interfere both C/A code and P(Y) code. In this research, the meaconing simulation environments are implemented using commercial software based GPS signal generator and GPS SDR. And the meaconing effects on signal acquisition and tracking of GPS receiver are analyzed according to the time delay of meaconing signal.
