Adaptive antennas with array processing are a promising technology for enhanced interference mitigation and detection in GNSS receivers. Especially in the field of safety critical applications, interference is a major concern. Therefore, the Institute of Communications and Navigation of the German Aerospace Center (DLR) started the development of a multi-antenna real-time GPS/Galileo receiver platform to demonstrate the performance gain of digital beamforming for GNSS receivers. To assess the performance and the capabilities of this receiver, several measurement campaigns in the Galileo test environment in Berchtesgaden were carried out. Especially the impact of radio interference on the receiver for different configurations was of great interest. This paper describes the measurements that were taken and the results that were achieved by the DLR multiantenna receiver.
