On the use of quickest detection theory for signal integrity monitoring in single-antenna GNSS receivers

Local threats such as radio frequency interference, multi-path and spoofing have attracted the attention of many researchers in the past years thus leading to a myriad of contributions in the field of threat detection. As a matter of fact, the current state of the art relies on classical detection techniques, which are not well suited for threat detection. In this paper, we take a leap forward in local threat detection, presenting a quickest detection framework for threat detection. The aim is to detect the presence of local threats as soon as possible in order to improve the integrity of GNSS receivers.
