Abstract
A position calculating method includes: determining a positioning satellite used for position calculation on the basis of at least reliability of satellite orbits in a prediction target period corresponding to a position calculation point, the reliability of satellite orbits being set in long-term predicted orbit data in which satellite orbits of positioning satellites and reliability of the satellite orbits are associated for each prediction target period; and calculating a position on the basis of a positioning signal received from the determined positioning satellite.
