Abstract
This paper addresses the problem of integrity monitoring in global navigation satellite system (GNSS) receivers. A new technique is proposed to quickly detect the presence of corrupted measurements caused by either multipath or spoofing threats. To do so, the symmetry of the correlation curve is permanently monitored, and a CUSUM-based sequential test is applied later on. Numerical results are provided to validate the technique and show its effectiveness.
