<P>PROBLEM TO BE SOLVED: To solve a problem that a coherent correlation cannot be executed beyond 20 msec when positioning data is unknown since inversion of correlation signals of I phase and Q phase can be caused for every 20 msec in a GNSS (Global Navigation Satellite System). <P>SOLUTION: A receiver includes a base station data detecting section for acquiring first positional data from data received by a base station GNSS signal receiving section, a base station GNSS signal generating section for generating a GNSS signal from the base station data detecting section, a mobile station GNSS signal receiving section for receiving the GNSS signal which is received by a mobile station and is transmitted from a mobile station, a correlation section for acquiring second positional data by performing a correlation operation between the generation data generated by the base station GNSS signal generating section and the reception data received by the mobile station GNSS signal receiving section, and an error detecting section for calculating a difference between the first positional data and the second positional data. The base station GNSS signal generating section corrects the first positional data so as to coincide with the second positional data. <P>COPYRIGHT: (C)2012,JPO&INPIT |
