Correction processing is performed to correct a position determination result obtained through dead reckoning, and a vehicle speed, a pitch angle, and a sensor mounting angle used in position determination executed through dead reckoning in a measurement period of GPS in accordance with direction-specific positional components and speed components of a vehicle, which are measured with GPS to determine a reliability of each of the direction-specific positional components and speed components of the vehicle and calculate an error index of a component determined to be a reliable component, to set the degree of contribution of a measurement component determined to be unreliable to correction processing to zero or almost zero, and to reduce the degree of contribution of a measurement component determined to be reliable to correction processing in accordance with a value of the error index."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Position sensing device and method","description":"A position sensing device and method are provided for executing correction processing based on a reliability and error index of each component of GPS output data to increase positioning accuracy.
