Japanese Patent JP7464790

B2

A positioning apparatus (100) includes: a first decoding unit (21) to detect pseudo ranges and carrier phase integrated values from ranging signals (L1C/A) for which augmentation information ([LC/A]) for correction is provided and to detect pseudo ranges and carrier phase integrated values from ranging signals (B 1 C) for which augmentation information is not provided; an error correction unit (27) to detect correction data ([LC/A]) for the ranging signals generated from the augmentation information and to correct the pseudo ranges and the carrier phase integrated values of the ranging signals (L1C/A) with the correction data ([LC/A]); and a positioning operation unit (25) to generate a first observation equation using the corrected pseudo ranges and carrier phase integrated values of the ranging signals (L1C/A), to generate a second observation equation using a time difference value between the pseudo ranges and a time difference value between the carrier phase integrated values of the ranging signals (B1C), and to perform positioning by executing a filter operation using the first observation equation and the second observation equation.
