Abstract

The invention provides map information updating device and method. The map information updating device is mainly used for simultaneously receiving signals, such as positioning signals and global position system (GPS) signals of mobile communication system signals or wireless network system signals, and then judging whether the GPS signals are converted to coordinate information, if the GPS signals are not converted to the coordinate information, the positioning signals are converted to the coordinate information and are updated to map data, and if the GPS signals are converted to the coordinate information, the coordinate information of the GPS signals is updated to the map data. The map information updating device and method can solve the problem that the general GPS positioning device is inconvenient for users to use due to low positioning and calculating speed and unstable signal reception.

Description

technical field [0001] The present invention relates to a map information update device and method, more specifically, a map information update device and method using GPS positioning technology. Background technique [0002] The global positioning system (Global Positioning System, GPS) can provide a wide range of applications, such as resource survey and detection, navigation and positioning, geodetic survey, cartography, position dynamic information, precise timing and so on. Commonly used by users is the function of location dynamic information. Using the GPS signal receiver and map database for calculation, the user's location can be displayed immediately. This is also the operation mode adopted by general map information update systems (such as GPS navigation devices). . However, the current GPS technology used in the map information update system has the following disadvantages: [0003] (1) When the GPS navigation device is turned on, it needs to wait for a period ...
