Abstract:
1. A wireless position detection system containing a mobile station, a base station for conducting wireless communication with the mobile station, multiple wireless receivers, and a server connected by way of a network to the base station and the multiple wireless receivers, wherein the mobile station contains a send/receive section for sending and receiving wireless signals at first and second antenna positions, the multiple wireless receivers contain a receive timing measurement section, each receive timing measurement section receives a reference signal sent from the base station to the send/receive section of the first and second antenna positions of the mobile station, measures the reference signal receive timing, receives the first and second mobile station signals sent from the send/receive section of the first and second antenna positions of the mobile station, measures the first and second mobile station signal receive timing, and conveys the reference signal receive timing and the first and second mobile station signal receive timing to the server, the server calculates the position of the mobile station based on the first and second mobile station signal receive timing, and the respective reference signal receive timing of the wireless receivers conveyed to the server from the multiple wireless receivers, and the mobile station send/receive section contains a first send/receive antenna and a second send/receive antenna at the respective first and second antenna positions.
