Abstract: Techniques are provided for improved precision timekeeping for a global positioning system (GPS) receiver. A methodology implementing the techniques according to an embodiment includes generating a system clock signal at a reference frequency, the system clock signal having a first frequency stability. The method also includes generating an auxiliary clock signal at an auxiliary clock frequency, the auxiliary clock signal having a second frequency stability that is greater than the first frequency stability, wherein the auxiliary clock frequency differs from the reference frequency by a frequency offset. The method further includes calculating corrections to the auxiliary clock signal based on a measure of error in the frequency offset and on an estimate of error in the auxiliary clock frequency. The method further includes using the calculated corrections to generate a timing signal, during absence of received GPS satellite signals (e.g., during times when less than four satellite signals are received).
