CRPAs (Controlled Reception Pattern Antennas) are becoming increasingly common, particularly in the Defense sector. CRPAs are an extremely effective anti-jam/spoof solution, because they adapt dynamically in response to jamming or spoofing signals. It is important to know the direction from which the interference is coming, so that you do not receive that RF power into your GPS receiver. This is done by forming nulls in the direction of the interference, or by using beam forming techniques to isolate and track only the true satellite signals, ignoring theothers.

This guide discusses the applications and use cases for CRPAs, how they work and the methods for testing them. It also explores the various types of testing solutions available in the marketplace today, and helps you choose the right solution for your specific application.
