Abstract:	An adequate design of the analogue frontend plays a crucial role for the achievable interference robustness of multi-antenna GNSS receivers. The behaviour of filtering, amplification and digital-to-analogue conversion are limiting factors for the effectiveness of all subsequent digital signal processing techniques. Any error in the analogue design which causes an information loss can never be entirely recovered by digital processing. This paper investigates the effect of typical hardware imperfections on spatial signal processing in multi antenna GNSS receivers.
