ABSTRACT
Controlled reception pattern antennas (CRPA) represent the state of the art in military GNSS antennas delivering mission critical PNT for the war fighter of today as well as tomorrow. Whilst the CRPA technology develops, the systems used for testing it also must undergo innovation.
Within this presentation we aim to give the audience a broad introduction into CRPA and their core functionalities especially regarding PNT resilience. We will then outline the key test methodologies, the according advantages and disadvantages as well as their common application across the development cycle of a CRPA.
Further to that we will then focus on the main threat vectors which a CRPA systems needs to be hardened against and summarize the key test requirements for assuring that the modern warfare demands are met. This will especially focus on spoofing and jamming.
Towards the end of the presentation, we will then introduce key technologies which CRPA units are often augmented with to further assure mission critical PNT. We will close in summarizing the test and test equipment requirements as well as introducing recent innovations in this sector.
