Abstract

The invention discloses a communication navigation data updating system which comprises a communication navigation server, a download terminal and a navigation terminal; wherein, the communication navigation server is used for receiving an update and download request of the download terminal, downloading target communication navigation data from a communication navigation database according to the update and download request, and sending the target communication navigation data; the communication navigation database is used for storing the communication navigation data which comprises map data stored in layers and in blocks; the download terminal connected with the communication navigation server and the navigation terminal is used for sending the update and download request to the communication navigation server, receiving the target communication navigation data sent by the communication navigation server, processing the target communication navigation data and sending the target communication navigation data to the navigation terminal; the navigation terminal is used for receiving the target communication navigation data sent by the download terminal and updating the existing communication navigation data. The communication navigation data updating system improves the rate of download and update and meets the rapid update requirements of users at the navigation terminal. The invention also provides a communication navigation data updating method.

Description

technical field [0001] The invention relates to the field of communication and navigation, in particular to a system and method for updating communication and navigation data. Background technique [0002] With the development of the Global Positioning System (GPS), navigation terminals using GPS have been installed on various objects requiring navigation, for example, in various vehicles such as airplanes, airplanes, automobiles, and the like. The navigation terminal receives radio waves indicating latitude, longitude, altitude, etc. from a plurality of GPS satellites, thereby calculating a current position of a movable object. The navigation terminal displays map information including the position of the movable object according to the stored communication navigation data. [0003] Nowadays, there are more and more navigation terminals and navigation systems that use communication and navigation data such as map data and road data to search for route guidance from a desir...
