The device may have wireless circuitry such as a global satellite navigation system receiver for receiving global satellite navigation system signals and for producing corresponding global satellite navigation system data. The global satellite navigation system data may include information on the current position of the portable electronic device. The portable electronic device may also have one or more sensors that are used to gather data in addition to the global satellite navigation system data. The sensors may include accelerometers and other devices capable of determining how the portable electronic device is oriented with respect to the Earth's magnetic field and how the device is being moved. When the device is moved, the movement and resulting change in orientation may be used in conjunction with the global satellite navigation system data to compute a current geographic location."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Location systems for handheld electronic devices","description":"An electronic device such as a portable electronic device is provided.
