In this paper, we propose a position sensing method (PSM), in which a single cross-loop inductive cable and three-phase receiving antennas are used, for high-speed trains with the linear synchronous motor (LSM). The proposed PSM is considered to be capable of detecting the realtime relative position to control a train traveling at speeds of up to 1000 km/h. The cross-loop inductive cable and receiving antenna are modeled and simulated to determine the optimum antenna dimensions. The signal processing unit is also simulated to obtain position information from the induced voltage in the three receiving antennas. The PSM with the use of a single cross-loop inductive cable and three-phase receiving antennas is tested by experiment, and it is found that the proposed PSM has great potential to detect the position of LSM-propelled 1000 km/h high-speed trains.
