ABSTRACT:
A mobile station (1) gets the carrier phase integration values and the code pseudorange which is based on the satellites' data transmitted from the satellites (SAT1-SATn). The mobile station (1) gets the data including the delay data of the ionosphere from a navigation message. And the mobile station (1) gets the data including the delay data of the ionosphere from data transmitted from a base-station, and fits data together. Utilizing these data from the two data sources, the mobile station (1) sets one linear regression equation and estimates the own position.
