Patent ID: 8487811

Claim:
A positioning-system device, comprising: a receiver configured to acquire and pull-in satellite data signals from which a geographic position of the positioning-system device can be determined, each of the satellite data signals including at least a time reference and ephemeris data that indicates an orbital position of a satellite; and a memory and a processor to implement a position solution service that is configured to: generate sync feedback, if the positioning-system device does not have a valid one of a bit sync or a frame sync, that includes a time-free position fix, the time-free position fix determined from: a satellite data signal; and approximate receiver time, the approximate receiver time maintained locally by a real time clock in the positioning-system device, the generating sync feedback occurring after signal pull-in of the satellite data signal and before at least one of the bit sync or the frame sync is obtained by the receiver; and utilize the sync feedback as a feedback input to determine at least one of the bit sync or the frame sync of the satellite data signal.
