PURPOSE: A positioning method using a weighted ridge regression is provided to solve the problem related to positioning of the terminal of a wireless mobile communication device and the like for distance measuring such as satellite distance measuring and/or wireless network distance measuring. CONSTITUTION: At least three distance measurement values are applied with WRP(Weighted Ridge Regression) process to determine the position of the terminal. For example, in an integrated satellite navigation system/wireless network, at least three distance measurement values are applied with the WRR process to determine the position of a mobile communication device. Here, at least one distance measurement value is that of satellite system(103) while at least one is that of wireless network system. The WRR process raises precision in determining position of a mobile communication device with a conventional minimum average square technology.
