GNSS Constellations Monitoring Using a Phased Array Antenna System
Year: 2025
Type: conference-paper
Abstract: This study presents a novel approach to enhance GNSS (Global Navigation Satellite System) signal reception using an eight-port beamformer tailored for satellite navigation applications. The beamformer architecture integrates key stages including filtering, amplification, phase shifting, and signal combination to optimize signal reception. For demonstration, a GNSS signal generator simulates a four-element phased array antenna, emitting GPS L1 constellation signals across four outputs connected to the beamformer ports. By manipulating phase settings on each port, the beamformer enables beam steering, showcasing improved signal detection. The results highlight the efficacy of the custom beamformer in enhancing GNSS signal reception and suggest promising implications for satellite signal tracking and navigation. This research contributes valuable insights into advanced antenna design and signal processing strategies for optimizing GNSS performance.
