Description

System and Method for Providing Navigation Informations}

The present invention relates to a navigation information providing system, and more particularly, to a navigation information providing system and a method for providing navigation information including a destination information managed by a navigation management server to a service user.

Mobile vehicles such as ships, aircraft, and automobiles are generally equipped with GPS positioning devices to check the current position and speed, or to determine the effective route. The GPS positioning device receives radio waves from a number of GPS satellites belonging to the Global Positioning System (GPS), calculates the position of the moving object using latitude, longitude, and altitude, and then includes the current position. Show map data to the driver. The navigation system is a system in which a vehicle receives location information from a GPS and informs a driver.

In general, the navigation system searches for the optimal route between the starting point and the destination through the map data, and continuously tracks the current position of the vehicle through the GPS satellites and performs route guidance to the destination. Route guidance is provided via the display screen or spoken through the speaker.

However, the navigation system only provides geographic information up to the address address input by the user, but does not provide the user with the destination information necessary for the destination, for example, a tourist destination, a hiking place, a food place, and the like. That is, the conventional navigation system provides only a fragmentary service for guiding a way to an input address, and thus has a very narrow service range.

And, in order to receive the route guidance, the destination must be entered in the navigation system. In the navigation system, since the input means is limited to the touch screen or several input buttons, the address is input by using a complicated key input procedure to set the destination. Therefore, when the driver inputs a destination while driving, the driver has a problem in that the surroundings are dispersed and the driving concentration decreases.

Meanwhile, in order to solve this problem, when the driver selects a destination by storing an address already input as a destination in a storage means of the vehicle navigation system, the address information previously input through a menu such as “recent road guide” is displayed. By selectively listing and selecting one of these, the driver may somewhat solve the inconvenience of having to repeatedly input the address.

However, this method has the following problems. The driver has not been remembered as the address of the destination, which is a combination of the number and the area name, for the destination guided by the route guidance. In this case, it is difficult to associate the corresponding destination through the address information provided by the navigation system.

Next, since it is difficult to display address information consisting of long strings on a single line through the display of a narrow navigation system, it is difficult for a driver to immediately grasp all the address information and thus it is not easy to select a destination.

In addition, since the navigation system receives location information from the GPS satellites, there is a problem in that the location information cannot be provided to the user when a communication failure occurs between the navigation system and the GPS satellites.
