A first bias conversion unit converts, based on a first frequency and a second frequency, a signal bias related to carrier phase for correcting a carrier phase contained in a first ranging signal having the first frequency, to a signal bias related to carrier phase for correcting a carrier phase contained in a second ranging signal having the second frequency. A first correction unit corrects the carrier phase using the converted signal bias. A second bias conversion unit converts the signal bias related to pseudorange to the signal bias related to pseudorange by making reference to a conversion table indicating values for use in conversion of the signal bias related to pseudorange to the signal bias related to pseudorange. A second correction unit corrects a pseudorange using the converted signal bias.

Positioning apparatus and augmentation information generation apparatus

Included are: a coaxial line () provided so as to pass through a second ground conductor (), a first dielectric substrate (), and a second dielectric substrate (), the coaxial line () including an outer conductor () allowing a first ground conductor (), a second ground conductor (), and a third ground conductor () to be conductive thereamong; and a conductive member () provided so as to pass through the first dielectric substrate (), the conductive member () allowing the first ground conductor () and the second ground conductor () to be conductive therebetween. An interface circuit () combines a plurality of signals having mutually different phases output from each of plurality of element antennas (), (), (), and () and outputs the combined signal to the coaxial line ().
