Abstract:	The paper focuses on the use of GNSS constellation simulators for the performance evaluation of advanced anti-jamming and antispoofing techniques of GNSS receivers using multiple antennas in an antenna array. The use of antenna arrays and array signal processing enables a GNSS receiver to apply extremely efficient countermeasures to counteract radio frequency interference. This enhanced resilience to jamming and spoofing makes the multi-antenna GNSS receivers very attractive in the context of safety-critical applications. The paper highlights the advantages of testing such receivers in a controlled laboratory environment by utilizing the multi-antenna GNSS simulators. A fully scalable architecture of the multi-antenna simulator based on the use of multiple simulator units is presented. The simulator composed of 8 single RF output simulators is used together with a GNSS multi-antenna receiver prototype (GALANT) developed by DLR in order to obtain exemplary results for beamforming, direction of arrival estimation and spoofing detection in the corresponding signal scenarios. The obtained results are also used to highlight the merits of a GNSS array receiver as part of promising anti-jam and anti-spoof solutions.
