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 (f ) of the processing unit ( ) with which the navigation device is fitted is adjusted to a plurality of so-called reduced operating frequencies (f , f , f , f ) lower than the normal operating frequency (f ) 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.
