Abstract
Technologies directed to estimating global navigation satellite system (GNSS) holdover time solutions are described. At a first time, at least four navigation messages are received. These navigation messages are used to determine an Earth-Centered, Earth-Fixed (ECEF) position. At a second time after the first time, less than four navigation messages are received. The ECEF position and an amount of time elapsed between the first and second times are used to determine a time solution corresponding to the second time. This time solution is used to synchronize a pulse per second (PPS) system to GNSS time.
