An architectural Description for a Car Navigation System
The Car Navigation System (CNS), as its name suggests, is a system or device to be used in cars and whose purpose is to provide real time (real time to be understood as opposite to store and forward) navigation information to its users.
The CNS implements supporting functions used to provide navigation information: GPS for positioning information and RDS for traffic information. In addition, the system makes use of digital maps encapsulated in an external SD Card to display its current position.
This document gives an overall view of the functionality offered by a CNS system as well as how internal software architecture may look like.
