Anti-jam Testing

Anti-Jam/CRPA Testing

Over the years a number of schemes have been developed to mitigate the effects of jamming and also the effects of unintentional interference effects. Testing such schemes requires specialized systems which stimulate the unit under test with GPS and simulated jamming/interference signals.

We have a range of test products to allow users to evaluate the performance of anti-jam systems in two different ways: (1) inside the chamber with the antenna or (2) outside of an anechoic chamber where the antenna electronics are exercised.

GPS Anti-jam Technology
What are the key validation and deployment issues of GPS Anti-jam Technology?

Despite their spread spectrum modulation, GPS satellite signals are vulnerable to interference because of their extremely low power (approximately -160 dBW). For many applications this vulnerability represents a significant problem. Anti-jam GPS receiver systems attempt to mitigate interference by using a variety of techniques including phase shifting, spectral filtering or adaptive beamforming. Evaluating the effectiveness of these techniques requires careful test planning—and the right equipment.
