In one example, a method of transferring precise absolute time from a satellite to a device includes receiving data from a messaging channel, wherein the data has a frame structure. The method also includes using the data to identify the satellite and a position of the satellite, correcting for signal time of flight using the satellite identity and the position, and using the data as a time reference to align a receiver clock to the frame structure. The method also includes, with the receiver clock aligned to the frame structure, receiving a precision time signal from the satellite, wherein the precision time signal comprises a periodic repeating code. The method also includes determining a timing phase of the code and using the timing phase to determine a precise absolute time."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Precise absolute time transfer from a satellite system","description":"Various techniques are provided for obtaining a precise absolute time using a satellite system.
