Method and terminal for providing a route in a navigation system using satellite image
First Claim
1. A terminal for providing a route in a navigation system using a satellite image, the terminal comprising:
- a route calculation unit for calculating the route from a starting location to a destination when a user inputs the destination;
a satellite image requesting unit for previously requesting a satellite image server for satellite images corresponding to image blocks showing contiguous segments of the route prior to displaying any of the requested satellite images and for downloading the requested satellite images from the satellite image server, wherein the route is divided into the contiguous segments contiguously extending from the starting location to the destination, each segment corresponding to one of the image blocks stored in the satellite image server;
a satellite image storage unit for storing the downloaded satellite images; and
a controller for retrieving, from the satellite image storage unit, a satellite image corresponding to a segment of the route on which the user is presently located and for displaying the retrieved satellite image.

Abstract
A method and a terminal for providing a route in a navigation system using a satellite image are provided. The terminal includes a route calculation unit for calculating a route from a current location to a destination when a user inputs the destination, a satellite image requesting unit for requesting a satellite image server for satellite images corresponding to locations on the route and for downloading the requested satellite images, a satellite image storage unit for storing the downloaded satellite images, and a controller for retrieving a satellite image corresponding to the current location from the satellite image storage unit and for displaying the retrieved satellite image simultaneously while downloading the satellite images corresponding to the locations on the route.
