Abstract (english): 
The received signals from GNSS satellites are low power and below the noise floor. Furthermore, GNSS antennas have low directivity to receive all signals simultaneously. Beamforming improves the carrier-to-noise density ratio (C/N0) before further processing by improving the directivity towards a specific satellite using an antenna array. Creating a beam for each satellite is processing intensive and leads to high costs. This paper presents a multibeam antenna array and software channel selection for low-cost beamforming for GNSS applications. Theoretical evaluations show benefits to signal gain and interference suppression, and practical results show an initial proof of concept.
