Sensor data for the portable device may be used to derive a navigation solution. Position information for the device may be estimated using the navigation solution. Map information for an area encompassing a current location of the user may also be obtained. Multiple hypotheses regarding possible positions of the portable device may be generated using the estimated position information and the map information. By managing and processing the hypotheses, updated estimated position information may be provided. The updated estimated position information may be provided as output or feedback to enhance the navigation solution."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for using map information aided enhanced portable navigation","description":"This disclosure is directed to enhancing the navigation solution of a portable device using map information.
