GPS RECEPTION DEVICE AND GPS POSITIONING CORRECTION METHOD

摘要

There are provided a GPS reception device and a GPS positioning correction method capable of judging a satellite signal affected by a multi path by a simple and sure method and correcting a measured position of a mobile station. A reference station (2) includes position correction data calculation means (5) and reference station reception intensity measurement means (6). A mobile station (3) includes positioning means (9), mobile station reception intensity measurement means (11), and positioning correction means (12). The reference station (2) transmits the position correction data and the satellite signal reception intensity at the reference station to the mobile station (3). The mobile station (3) compares the reception intensity at the reference station to the reception intensity at the mobile station for each of the satellite signals of the satellites. When the difference is equal to or above a predetermined threshold value T1, the satellite signal of the satellite is excluded from the positioning satellite signal.
