Comparison of Radiated A-GNSS Sensitivity Measurement and Stand-alone GNSS Tracking Sensitivity Measurement

The Global Navigation Satellite System (GNSS) underpins a wide range of applications, from vehicle navigation to precision agriculture. There is growing interest in enhancing GNSS acquisition and tracking sensitivity to enhance user experience in challenging environments. The GNSS sensitivity measurement is crucial for verifying receiver reliability and accuracy, especially for weak signals. This paper presents a comparative study of A-GPS and GPS receiver sensitivities by performing radiated A-GNSS sensitivity measurement and standalone GNSS tracking sensitivity measurement.
