An implementation of a robust vector phase-locked loop (VPLL) for joint tracking of carrier phase from the navigation satellites in the event of ionospheric scintillation is presented. This partitioned tracking method leads to an increased tolerance to ionospheric disturbances due to scintillation in the carrier phase tracking, providing a trade off between the pure VPLL and the classic scalar tracking...
The aim of this paper is to investigate an innovative carrier tracking scheme capable of maintaining the robustness characteristics typical of the Kalman filter tracking loop architecture and, at the same time, reducing the computational load due to the burdensome operations needed by the legacy Kalman filter implementation. Computationally speaking, the heaviest stage of the Kalman filter scheme...
