Abstract
A method of computing navigation information in a portable device comprising a GNSS receiver arranged to receive navigation signals from a plurality of navigation satellites, and a GNSS processor to extract a GNSS position information from said navigation signals. The GNSS receiver is also arranged to obtain image data from a camera module. The method comprises the steps of: deriving a set of position information from the camera module; providing the camera-derived position information to a navigation processor; using said set of camera-derived position information and said navigation signals, to generate a position fix of the GNSS receiver; computing navigation information based on said generated position fix.
