  • Method for operating a plurality of GNSS receivers for detecting satellite signal deformation
    Patent number: 11409002
    Abstract: A test metric for satellite sent GNSS code signals is proposed, wherein a signal sent by each satellite i is received at different GNSS receivers, and bias-removed, averaged over the receivers and normalized measurement values are derived out of autocorrelation function values. A correlation matrix Ri,n is built from a matrix Xi,n containing the measurement values in the form of measurement value vectors {right arrow over (X)}i,k from the present time epoch tn and from previous time epochs tk with k=1, . . . , n?1, wherein a principal component analysis is done of matrix Ri,n, wherein a transformed vector {right arrow over (T)}i,n=PCi,nT·{right arrow over (X)}i,nT is calculated, with PCi,n containing at least two eigenvectors having the largest eigenvalues of all eigenpairs.
