In this paper, we compared and analyzed the performance of generated GPS signal by GPS L1 signal generator with Live GPS signal using the U-Blox receiver. Generally GPS Receiver calculates the position of the satellite by using the ephemeris data received from GPS satellites, and calculates the position of the receiver using the pseudorange. GPS satellites, so it is synchronized, it will then transmit...
In this paper, we analyze the effect of error of code tracking and frequency tracking according to the chip delay of spoofing signal through the simulation. Firstly, we investigate the type of spoofing signal and defense technical of spoofing attack. For simulation, we generated the intermediate spoofing signal using the software GNSS signal generator simulator(SGGS), the intermediate spoofers synchronize...
