Abstract: Methods and apparatus for generating a test signal for a PNT configuration, and for testing a PNT configuration are disclosed. One such method comprises the steps of using one or more GNSS jamming signal detectors (100) to detect at least three different types of threat signal, each being an RF -based man-made GNSS jamming signal, and recording, to a database, information for the threat signals; receiving, from the database, information for at least one of the threat signals; generating a corresponding threat signal from the received information; and combining the corresponding threat signal with a PNT signal via a signal combiner to generate the test signal.
