摘要
A parameter calculating method includes: setting lengths of prediction target terms as divisions of a predetermined effective period of a satellite orbit as variable lengths; and calculating a parameter of a predetermined orbit model expression used for approximating the satellite orbit based on prediction position data containing prediction positions of a positioning satellite in time series for each of the prediction target terms.
