Abstract
In this paper, we analysis 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 its counterfeit GPS signals with the current broadcast GPS signals. The software GPS receiver simulator(SGRS) received the spoofing signal and normal signal from SGGS, and process the signals. In paper, we can check that the DLL and PLL tracking loop error are generated and pseudo-range is changed non-linear according to chip delay of spoofing signal when the spoofing signal is entered. As a result, we can check that navigation solution is incorrectly effected by spoofing signal.
