Abstract
A method of dynamically optimizing the update rate of GPS output data has acts of setting relationships between different moving speeds and different update rates; sensing a current moving speed of a GPS receiver; determining a update rate corresponding to the current moving speed of the GPS receiver; and outputting GPS position and velocity data according to the determined update rate. Since the update rate is variable in view of moving speed, a moving map showing GPS information remains a smooth display.
