Abstract
A correction data creation unit receives a value of an error used in satellite positioning at a first time interval, and receives a correction value of the error at a second time interval that is a time interval 1/n (n is an integer of two or larger) time interval of the first time interval. The correction data creation unit also corrects the value of the error at the second time interval by using the correction value.

17. A positioning device comprising:
-
a receiving unit to receive a value of an error used in satellite positioning at a first time interval and receive a correction value of the error at a second time interval that is 1/n (n is an integer of two or larger) time interval of the first time interval; and an error correction unit to correct the value of the error at the second time interval by using the correction value, wherein the receiving unit receives at the first time interval a value of a frequency-dependent error that is an error dependent on a frequency of a carrier from a positioning satellite and a value of a frequency-independent error that is an error independent of the frequency of the carrier and receives, at the second time interval, a correction value of the frequency-independent error, and the error correction unit corrects the value of the frequency-independent error at the second time interval by using the correction value. - View Dependent Claims (18, 19, 20, 21, 22, 23)

- 24. A positioning device comprising a positioning calculation unit to perform positioning calculation by using a state quantity including at least either an ionospheric residual or a tropospheric residual that remains after error correction processing is performed on observation data from a positioning satellite.
