An anti-jamming GNSS (Global Navigation Satellite System) receiver performs to minimize received jamming signals. This paper introduces test methods of the anti-jamming GNSS receiver in multi-jamming environments using the anechoic chamber and car driving tests. For the anechoic chamber test, we propose test techniques based on one of Spirent GPS simulators, GSS7790 simulating GPS L1CA and L2C signals, and install the multi-jamming signal generators consisting of the four CW (Continuous Wave) and four AWGN (Additive White Gaussian Noise) jammers in turns. For the car driving test, we install test equipments applying real angular velocity and jamming incidence angle for actual operational environments. The proposed test methods are mutually complemented its shortage and very useful techniques to verify anti-jamming receivers.
