Abstract:	Galileo signals have interference protection to some degree due to their code structure. However, since signals transmitted from satellites reach the receiver antenna with a very low signal power and considering that the noise level is much higher than the signal power (around 20 dB), they are vulnerable to interference. Thus, various interference mitigation methods are required in the receiver, especially for Safety of Life (SoL) applications where integrity and accuracy of the signal is significant. In addition, ICAO provides requirements in [12] that states the estimated C/N0 should be above the minimum required C/N0 depending on the desired signal characteristics and no loss of lock on carrier phase tracking occurs in the receiver. In this study, several precorrelation techniques based on a single antenna element have been analyzed that detect and suppress the interference signal on real-time GIOVE signal.
