摘要：A method and apparatus for determining a drift between a local clock of a
movable device and a reference clock that is used by one or more reference devices. The
local clock may be calibrated at a calibration location and then the movable device may
be moved to an operating location that is different from the calibration location. The
drift is determined by observing one or more signals transmitted by the respective one
or more reference devices, when the device is at the calibration location and when it is at
the operating location. These observations are used together with a model of the signals
to determine the drift.
