dc.description.abstractA frequency lock loop (FLL) and a phase lock loop (PLL) are used to track the carrier in a GNSS receiver. In order to meet the most stringent positioning and navigation requirements, several receiver architectures have been proposed for global navigation satellite system (GNSS) including stand-alone receivers or GNSS receivers integrated with inertial navigation systems (INS). Basically, there are four receiver architectures, namely, standard receivers, estimator-based receivers, vector-based receivers, and ultratight receivers. The objective of this work is to reduce the camer phase reacquisition time usmg advanced receiver architectures. This paper looks at how different receiver architectures can be used or modified to more rapidly reacquire carrier phase tracking, thus providing more measurements that can be used for high-accuracy positioning applications. This contrasts with other work which has focused more on reacquiring range capability. Specifically, a piece-wise control method and a phase prediction architecture are proposed. The piece-wise method takes advantage of different parameters in the control system to produce different transition performance within the tracking loop. With this in mind, the approach divides the reacquisition process into separate periods each with different control system parameters in order to achieve a faster transition process. In the phase prediction architecture, carrier phase measurements are predicted for satellites that have lost lock by integrating the estimated Doppler computed from the navigation solution. Predicted phase quality is evaluated in both empirical and theoretical ways. All algorithms are tested usmg real data collected under mild to moderate operational conditions.
