Abstract:	The objective of this work is to reduce the carrier phase reacquisition time using a phase prediction method in the standard and advanced receiver architectures. In the phase prediction approach, carrier phase measurements are predicted for satellites that have lost lock by integrating the estimated Doppler computed from the navigation solution. In so doing, the predicted phase error is typically accurate enough to yield significant improvements in phase reacquisition times. Predicted phase quality is evaluated and all algorithms are tested using real data collected under mild to moderate operational conditions. Standard, vector-based, and ultra-tight architectures are considered.
