    The invention discloses a hyperbolic positioning method, which comprises: a. according to signal coverage of reference subzone, determining and measure adjacent subzone; according to measured result, calculating the transmission time difference between said two subzones; b. according to result and geometric distribution relation of subzones, selecting obtained time difference to satisfy determined request; c. using selected time difference to take hyperbolic position calculation, and obtaining positioning result. This method can increase position estimation precision effectively, and decreases computing complexity.
