Abstract

The present invention is a combination of GPS (Global Position System) and GSM (Global System for Mobile Communication) navigation system. By using the data of GPS and SMS (Short Message Service), the present invention can display navigation directions and relative positions and send short message with positions. Therefore, a navigation system with active navigation guiding and help seeking is provided.

Claims

1. A navigation system comprising:

a destination setting module for setting the location of default destination;

a GPS module for receiving coordinates data of global positioning satellite;

a SMS module for sending text messages containing current location information obtained from said GPS module;

a destination guiding module for guiding users forward toward said default destination; and

an electronic compass module for calibrating the navigation system position;

characterized in that the said destination guiding module can directly indicate the direction of said default destination and the distance between said default destination and current location.

2. A navigation system according to claim 1, wherein said destination guiding module can indicate the direction and distance of said default destination without the need of electronic map.

3. A navigation system according to claim 1, wherein said SMS module can receive text messages from other phone to control the operation of the navigation system.

4. A navigation system according to claim 1, wherein said destination guiding module can use images or voice instructions indicating the direction and distance of said default destination.

5. A navigating method comprising:

destination setting function for setting the location of default destination;

GPS function for receiving coordinates data of global positioning satellite;

SMS function for sending text messages containing current location information obtained from said GPS module; and

destination guiding function for guiding users forward toward said default destination, characterized in that the said destination guiding function can directly indicate the direction of said default destination and the distance between said default destination and current location.

6. A navigating method according to claim 5, wherein said destination guiding function can indicate the direction and distance of said default destination without the need of electronic map.

7. A navigating method according to claim 5, further comprising:

electronic compass function for calibrating the navigation system position.

8. A navigating method according to claim 5, wherein said SMS function can receive text messages from other phone to control the operation of the navigation system.

9. A navigating method according to claim 5, wherein said destination guiding function can use images or voice instructions indicating the direction and distance of said default destination.
