Claim Text:
1. A method of determining a global position of a worn biometric monitoring device comprising a navigation data receiver, the method comprising: (a) periodically and automatically syncing the worn biometric monitoring device with a secondary device associated with the worn biometric monitoring device, wherein the periodic and automatic syncing comprises repeatedly providing the worn biometric monitoring device with current ephemeris data from the secondary device using a wireless short-range, low-power communication protocol according to a schedule, wherein the current ephemeris data contains information about current satellite positions usable for position fixing; (b) determining that a global position of the worn biometric monitoring device should be calculated; and (c) calculating the global position of the worn biometric monitoring device using the current ephemeris data and data received by the navigation data receiver.
