Robust GPS-based timing for phasor measurement units based on single-receiver and multi-receiver position-information-aided vector tracking
… implement the position-information-aided (PIA) vector tracking loop and the multi-receiver PIA vector tracking loop. To evaluate the effectiveness of the algorithms presented in this thesis, we also conduct field experiments which showed improve tracking capabilities and continued operation …

Improving the robustness of GPS direct position estimation
… Unlike conventional methods, such as scalar and vector tracking, DPE performs Maximum Likelihood Estimation (MLE) of the navigation solution on the raw GPS signal. DPE initializes multiple navigation candidates and searches for the candidate that maximizes the cross-correlation between the …

Attack resilient GPS based timing for phasor measurement units using multi-receiver direct time estimation
… existing techniques such as traditional scalar tracking and Position-Information-Aided Vector Tracking.

Contributions to a Context-Aware High Sensitivity GNSS Software Receiver
… and severe multipath fading degrade the signal tracking performance and limit the use of GNSS in indoor and urban environments. Therefore, this thesis focuses on enhancements of a context-aware high sensitivity software GNSS receiver. To improve the GNSS signal tracking sensitivity, three levels …

A Multi-Constellation Multi-Frequency GNSS Software Receiver Design for Ionosphere Scintillation Studies
… of this work is the implementation of a Vector tracking loop (VTL) for robust carrier tracking. The VTL is developed based on the extended Kalman filter (EKF) with adaptive covariance matrices. Both scalar tracking loop (STL) and VTL are implemented. Once an error in the scalar loop is …
