測位装置
Document Type and Number:
Japanese Patent JP7125359
Kind Code:
B2
Abstract:
To accurately determine a position of a wireless terminal.SOLUTION: An information processor 20 executes: information acquisition processing for acquiring, from a wireless terminal 12, a distance measurement value between each of three stationary stations 14-1 to 14-3 and the wireless terminal 12; distance correction processing for sequentially executing correction on two distance measurement values out of three distance measurement values, for three combinations which select two of the three distance measurement values; and position determination processing for determining the position of the wireless terminal 12 on the basis of the three distance measurement values after the distance correction processing has been executed. The distance correction processing includes geometrical correction processing which determines a geometrical relation between two circles that are respectively centered at positions of two stationary stations for which two distance measurement values have been determined and that have the two distance measurement values as their radii, and corrects the two distance measurement values on the basis of the determination result.SELECTED DRAWING: Figure 1
