To provide a satellite positioning/calculating method and a satellite navigating/positioning device using the same, having characteristics less affected by a multipath, moreover dispensing with a processor having high processing capacity as a computing portion, having a small-sized signal processing function with less power consumption, and capable of determining an integer bias in real time.
Within the extent of a relational expression obtained at each observation time, a positioning/computing device 104 finds an expression in which variables are eliminated equating to a positioning side position and a phase difference used as reference in carrier phase observation. By applying the found expression to the original relational expression, a conditional expression is found in which variables are eliminated equating to a positioning side position and a phase difference used as reference in carrier phase observation. Each time observation is made, an integer bias is found with respect to the conditional expression in which the variables found about a plurality of times of observation including prior ones are eliminated on condition that the expressions together hold with deviations as small as possible.
