摘要

PROBLEM TO BE SOLVED: To provide a position information system that can enhance the position calculation accuracy.;SOLUTION: The position information system decides a reference face on the basis of the altitude of a base station and a range corresponding to the electric field strength and assumes that a measured position exists on the reference face to calculate the measurement position on the basis of the electric field strength. As a result, since the position is calculated by taking into account the altitude information, the calculation accuracy can be enhanced.;COPYRIGHT: (C)2002,JPO
