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.

Claims

1. A method of dynamically optimizing the update rate of GPS output data, the method comprising:

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.

2. The method as claimed in claim 1 further comprising an act of receiving the position and velocity data and accordingly updating a moving map showing GPS information.

3. The method as claimed in claim 1, wherein the update rates are in direct proportion to the moving speeds.

4. The method as claimed in claim 2, wherein the update rates are in direct proportion to the moving speeds.
