Development and analysis of a parallelized direct position estimation-based GPS receiver implementation
Theoretical results conclude that one-step Direct Position Estimation (DPE)-based Global Navigation Satellite System (GNSS) receivers can achieve more accurate localization than their two-step counterparts. However, numerical solutions to DPE equations and approximations made for those equations …

Improving the robustness of GPS direct position estimation
Global Positioning System (GPS) receivers are increasingly used for positioning in urban environments and precise timing in critical infrastructures. These scenarios are challenging for GPS receivers because building reflection and obstruction contribute to GPS signal degradation in urban …
