The mobile station transmits a first radio signal S1 and the reference station transmits a second radio signal S2 multiple times. Each of the fixed stations extracts a first phase difference based on the first radio signal S1 and extracts second phase differences based on the second radio signals S2. The server calculates time variations of the second phase differences based on the multiple second phase differences to calculate a third phase difference. The server cancels phase offset by the respective fixed stations using phase difference information between the mobile station and the respective fixed stations and phase difference information between the reference station and the respective fixed stations and acquires distance information between the respective fixed stations and the mobile station to calculate the position of the mobile station."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Position detection system and position detection method","description":"A position detection system includes a mobile station, a reference station, fixed stations to, and a server.
