The train position detection apparatus includes: a memory that stores therein in advance a railway design standard of a railway track on which the train travels; and one or more hardware processors that detect a position of the train by self-contained navigation based on an input signal from a self-contained navigation sensor. When a result of the train position detection based on the positioning radio waves does not satisfy the railway design standard, the one or more hardware processors correct the result of the train position detection based on the positioning radio waves with a result of the position detection by self-contained navigation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Train position detection apparatus and method","description":"A train position detection apparatus is configured to detect a position of a train by receiving positioning radio waves from satellites through a reception antenna.
