Abstract
Aspects of the disclosure provide an apparatus that includes a sensor module and a navigation signal receiver. The sensor module is configured to generate signals indicative of motions of the apparatus. The navigation signal receiver includes receiver circuitry and processor circuitry. The receiver circuitry is configured to receive satellite navigation signals from a plurality of satellites. The processor circuitry is configured to determine a velocity of the apparatus based on the satellite navigation signals, receive an estimated speed from the sensor module, calibrate a moving speed based on the velocity and the estimated speed, and determine a power saving time based on the calibrated moving speed. The power saving time is an amount of time that the navigation signal receiver is to stay in a power saving mode.
