Abstract: In one embodiment during a warm-start mode, an estimator estimates a satellite correction signal based on satellite orbit data, satellite clock data, and satellite bias correction data derived from stored received raw satellite signal measurements. A data source selector seamlessly switches a measurement data source from the stored received raw satellite signal measurements to live, real-time raw satellite signal measurements if or when a respective measurement time tag of a last-processed one of the stored received satellite signal measurements approaches or reaches the current time.
