Abstract: A method, non-transitory computer readable medium and timing computing device for subnanosecond time synchronization. A difference between synchronized measurements of one of a plurality of satellite signals from a reference receiver and another receiver for each of N values within a cycle is determined. A clock bias error is calculated for each of the N values. The calculated clock bias errors are stored in a vector over time for each of the N values, with one of the vectors for each of the N values. A trajectory of the vectors over time is determined. The one of the vectors with a best convergence over time is selected. A timing signal is adjusted based on the N value for the selected one of the vectors with the best convergence over time.
