Patent abstract
A set of global navigation satellite system receivers is deployed in and moves about a region that may be occupied by a signal jammer or spoofer. The receivers collect truth data from spectral content of the broadcast satellite signal and, optionally, from a set of sensors associated with each receiver from which an independent determination of location can be derived. The truth data are compared with data acquired by the receivers and an alert is issued upon detection of an anomaly. The data from receivers in a region of influence of the jammer or spoofer are aggregated, integrated, and correlated to generate a two-dimensional representation of a region in which the offending signals are present.
