dc.description.abstractVector-based GNSS (VBGNSS) receivers attempt to bridge the gap between Assisted GNSS (AGNSS) and High Sensitivity GNSS (HSGNSS); AGNSS use satellite orbit and network time information to predict the incoming satellite frequency during signal acquisition while HSGNSS enables the tracking of GNSS signals with strong attenuation. Similar to AGNSS, VBGNSS receivers make use of both satellite and receiver navigation information (position, velocity, and clock) to better estimate the incoming signal frequency and code-phase to improve the tracking sensitivity of weak GNSS signals. The performance of VBGNSS receivers is proportional to the navigation solution accuracy; this research focuses on improving the performance of VBGNSS receivers using Ultra-Wideband (UWB) ranging and Differential GPS (DGPS) corrections. From the results presented herein, it was found that UWB ranging can improve the tracking sensitivity, position availability, and accuracy of a VBGNSS receiver; likewise DGPS can improve VBGNSS receiver performance in certain operating environments.en_US
