Method and System for Providing a Navigational Instruction for a Route From a Current Location of a Mobile Unit to a Target Position

A method for providing a navigational instruction for a route from a current location of a mobile unit to a target position is disclosed. Location environmental data are detected in a first detection region by means of the mobile unit. Reference environmental data are detected in a second detection region. Based on the location environmental data and the reference environmental data, at least one common environmental feature is determined, wherein the common environmental feature is arranged both in the first detection region and in the second detection region. A relative arrangement of the mobile unit relative to the target position is determined and the navigational instruction is generated and output based on the relative arrangement. A system for providing a navigational instruction for a route from a current location of a mobile unit to a target position comprises a mobile detection unit, a reference detection unit, and a processing unit.
