POSITIONING RECEIVER AND POSITIONING METHOD FOR USER EQUIPMENT

摘要

A positioning receiver and a positioning method for user equipment in which errors in the position when the position of the user equipment is calculated can be reduced even in an environment in which the user equipment moves at high speed to improve the accuracy of the position. User equipment (UE) (100) calculates the Doppler shift amount of the pseudo distance data and carrier wave between base stations (BS-1, BS-2, BS-3, ) on the basis of the communication between the base stations (BS-1, BS-2, BS-3, ) and calculates a position coordinate from the pseudo distance data between the base stations (BS-1, BS-2, BS-3, ), provided that the pseudo distance data obtained between the base stations in which the calculated Doppler shift amount is larger than a reference value is not used for the calculation of the position coordinate.
