  • Method for controlling a navigation device and navigation device implementing the same
    Patent number: 6694276
    Abstract: There is described a method for controlling a navigation device, such as a satellite navigation device like a GPS, GLONASS, GALILEO or other receiver, and a navigation device allowing this control method to be implemented. According to the invention, the operation of the navigation device is adjusted as a function of a measurement of the velocity (v) of the navigation device for the purpose of saving energy. In particular, the operating frequency (fck) of the processing unit (18) with which the navigation device is fitted is adjusted to a plurality of so-called reduced operating frequencies (fck2, fck3, fck4, fck5) lower than the normal operating frequency (fck1) as a function of the value of the velocity measurement (v). The invention is intended in particular to allow a navigation device to be integrated in a portable object of small volume powered by a battery or a rechargeable accumulator, such as a timepiece.
