| Resum: | Global Navigation Satellite Systems (GNSS) are the primary technology for delivering reliable positioning and timing solutions, supporting a wide range of applications across different sectors. However, their performance can be significantly degraded by interference, which gives rise to the need for robust countermeasures that ensure both accuracy and resilience. This paper presents a testbed based on the Skydel GNSS Software Simulator for conducting multi-antenna GNSS experiments under real-world conditions, enabling interference mitigation studies without the need for additional hardware. The output is adjusted and sent to the FGI-GSRx GNSS software receiver, which evaluates the impact of the beamforming algorithms across all receiver stages, providing a comprehensive assessment of their effect on positioning performance. Two well-known techniques, Power Inversion (PI) and Capon (CAP), are analyzed within the context of small receivers, with results demonstrating their potential for interference mitigation even with limited antenna arrays, thus proving their suitability for handheld devices. |
