Abstract
Methods and apparatus for detecting, geo-locating and/or classifying a GPS or GNSS jamming signal are disclosed. One such method comprises the steps of analysing a spectrogram of the jamming signal using a tree-based decision process and as a result, then selecting one of a number of types of jamming signal, wherein one of the decisions (1103) in the tree is whether the spectrogram has spectral periodicity.
