Method and apparatus for automatically optimizing and setting a GPS reception period and map contents
First Claim
1. A method for automatically setting a navigation function in a navigation system having a Global Positioning System (GPS) receiver, the method comprising:
- receiving a GPS signal through the GPS receiver in a first period;
measuring a moving speed of a GPS terminal using the received GPS signal; and
updating the first period by considering the first period and a second period based on the measured moving speed of the GPS terminal.

Abstract
A method and apparatus for Global Positioning System (GPS) navigation is configured to automatically set an optimal GPS reception period and optimal map contents according to a moving speed of a user in a navigation system using a GPS terminal. When the moving speed of the user is considered, power efficiency is increased by optimizing a GPS reception period in terms of hardware and system load is decreased by reducing an unnecessary system operation in terms of software. User convenience is maximized by optimizing map contents requested by the user according to a moving speed in real time and displaying the optimized map contents.
