In a locator device, a dead reckoning part calculates a position of a subject vehicle by dead reckoning. A pseudorange smoothing part smooths a pseudorange between a GNSS satellite and a position of the subject vehicle using a carrier wave phase of the GNSS satellite. A GNSS receiver positioning error evaluation part evaluates reliability of the position of the subject vehicle calculated by the multi-GNSS receiver. A GNSS positioning part (Kalman Filter (KF) method) calculates a position of the subject vehicle from a smoothed value of the pseudorange, a positioning augmentation signal, and an orbit of the GNSS satellite. A complex positioning part (KF method) calculates an error in the dead reckoning from the position of the subject vehicle calculated by the GNSS positioning part (KF method), and corrects the position of the subject vehicle calculated by the dead reckoning part based on the error in the dead reckoning.

A code positioning part calculates a position of a subject vehicle and a receiver clock based on an orbit of a GNSS satellite in which an error indicated by a positioning reinforcing signal is corrected and a first corrected pseudorange being a pseudorange of the GNSS satellite in which an error indicated by the positioning reinforcing signal is corrected. A receiver clock bias error correction part determines a difference between a two-point range between a position of each of a plurality of GNSS satellites and the position of the subject vehicle and the first corrected pseudorange as an unknown error, and determines a receiver clock bias error of the pseudorange based on the unknown error. A code positioning correction part recalculates the position of the subject vehicle, using a second corrected pseudorange that is obtained by correcting the first corrected pseudorange using the receiver clock bias error.
