Positioning apparatus, GNSS receiver, information terminal device, positioning method and program

摘要

A positioning apparatus is provided that may include a pseudo distance measurement unit that measures the pseudo distance between the positioning satellite and the antenna, an ionosphere delay amount calculating unit that calculates an ionosphere delay amount included in the pseudo distance, and a pseudo distance corrector that executes a positioning calculation by correcting the pseudo distance based on the ionosphere delay amount. The ionosphere delay amount calculating unit sets the upper limit of the partition number between the positioning satellite and the antenna, determines the total number of electrons sTEC by integrating in the range of less than the upper limit of the partition number, and calculates the ionosphere delay amount based on the determined total number of electrons sTEC.

1. A positioning apparatus that executes positioning based on signals received by an antenna of a GNSS receiver from a positioning satellite, comprising:
a pseudo distance measurement unit configured to measure a pseudo distance between the positioning satellite and the antenna; an ionosphere delay amount calculating unit configured to calculate an ionosphere delay amount included in the pseudo distance; and a pseudo distance corrector configured to execute a positioning calculation by correcting the pseudo distance based on the ionosphere delay amount; wherein the ionosphere delay amount calculating unit sets an upper limit of a partition number between the positioning satellite and the antenna, determines a total number of electrons by integrating over a range up to the upper limit of the partition number, and calculates the ionosphere delay amount based on the determined total number of electrons.
