Abstract: This paper presents the experimental results for the effect of Out-of-Band (OOB) interference on Radio-Navigation Satellite Service (RNSS) receivers in the S-band. In areas not included in NavIC's service area, there is a limit to analyzing the effect of S-band OOB interference on real RNSS signals. Therefore, we imitate the OOB interference environment in the S-band and then analyze the OOB interference effects on the L-band RNSS signals. The OOB interference signals, such as Long Term Evolution (LTE), WirelessFidelity (Wi-Fi), and the microwave oven signals, are recorded by the USRP, and re-radiated in the L-band. The experiment results show that the OOB interference may induce severe degradations on the performance of RNSS receivers.
