<p><P>PROBLEM TO BE SOLVED: To obtain a moving-body positioning method and to obtain a moving- body guidance method using a positioning result. <P>SOLUTION: A transmission signal is transmitted from a moving body, a plurality of receiving stations whose times are synchronized are provided on the ground, the receiving time of the transmission signal from the moving body received by each receiving station is found for each receiving station, and nonlinear simultaneous expressions are found on the basis of a receiving-time difference between two receiving stations. The receiving-time difference is found on the basis of a maximum value of a cross-correlation value in a received waveform between the two receiving stations, the maximum value of the cross- correlation value uses a phase inversion part, a three-dimensional position and a two-dimensional position of the moving body are positioned, their data are transmitted to the moving body as a guidance signal, and the moving body is guided. Consequently, the position of the moving body is positioned precisely by a simple apparatus, and three-dimensional position data and two-dimensional position data are used to guide the moving body for approaching and to guide the moving body on an airport face. <P>COPYRIGHT: (C)2004,JPO</p> |
