Abstract
A power saving device for a GPS device is to utilize acceleration of gravity sensor to continue detecting the acceleration variation of the GPS device; if an acceleration value is larger than a threshold value, a GPS signal receiver is then started; if the acceleration value is smaller than the threshold value, the GPS signal receiver is then shut. This allows the GPS device to be power saving and not need to facilitate an extra oscillation switch therein to save the production cost.
