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.

摘要： When a frequency measurement unit measures the frequency of a temperature-sensing oscillation test signal and the frequency of a driving-pulse signal transmitted from an electronic apparatus via an coil electromagnetically coupled with a motor coil, a temperature-compensation data generation unit creates temperature-compensation data based on the frequency of the temperature-sensing oscillation test signal and the frequency of the driving-pulse signal. This temperature-compensation data is transmitted to an analog electronic timepiece via the coil. That is, a state of the analog electronic timepiece is measured in a non-contact manner and the temperature-compensation data obtained based on the measurement result is transmitted, whereby the analog electronic timepiece is adjusted in a state of being incorporated in an external casing.

摘要： A GPS-based frequency/time source of the present invention provides an accurate, traceable low cost reference. In particular, the GPS-based frequency/time source includes a GPS receiver, a variable frequency oscillator and a micro processor. The GPS receiver receives and produces as output signals GPS information, whereas the variable frequency oscillator has a frequency control input terminal and produces an output frequency signal, and is coupled to the GPS receiver. The micro processor is coupled to receive the output signals produced by the GPS receiver and produces an error signal indicative of a difference in frequency between GPS synchronized frequency and the output frequency signal of the variable frequency oscillator. Circuitry is responsive to the error signal to produce an electronic frequency control signal, which is applied to the frequency control input of the variable frequency oscillator so as to cause the difference in frequency to be reduced. In this manner, a low cost oscillator may be employed in such a way as to produce a very accurate output frequency signal.
