The satellite data signals each include a time reference and ephemeris data that indicates an orbital position of a satellite. A sync feedback is generated that includes a time-free position fix determined from a satellite data signal before bit sync and/or frame sync of the satellite data signal are obtained. The sync feedback is then utilized as a feedback input to determine the bit sync and/or the frame sync of the satellite data signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Sync feedback for time to first fix","description":"In embodiments of sync feedback for time to first fix (TTFF), satellite data signals are received from which a geographic position of a positioning-system device can be determined.
