A multitude of antenna radiation patterns generated from a modal antenna provide the capability to optimally acquire GPS signals across a wide range of angles of arrival. Minimum radiation pattern roll-off is observed from the composite pattern generated from the multiple patterns. An algorithm is described that reduces the acquisition time for a location fix for cold and hot start conditions."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"GPS location system using modal antenna","description":"A modal antenna is implemented to provide a variable radiation pattern for improved global positioning system (GPS) signal reception.
