NAVIGATION METHOD USING GEOGRAPHIC LOCATION CODES

摘要

A user accesses (110) a navigation server and inputs an indication of position of his premises or other location down to the level of the access point. The navigation code is stored (111) and it is downloaded to the user. When the user loads it to his client system or device the navigation code is automatically tested (113). The generated navigation code is predictable and is automatically tested on every occasion at which it is received by a device or system. This helps to ensure integrity of the navigation system, allowing a wide range of devices or systems to handle the navigation codes. After validation, a quality indicator is also generated. The navigation device converts (115) the navigation code to a machine-level geographic code for use in generating onboard navigation instructions (116) for the driver. At the destination the navigation performs hand-shaking with a destination device (117) and there is communication to validate a delivery.
