PURPOSE: A method for correcting an estimated position value by selecting the measured value of pseudo distance is provided to optimize the selection of a hardware which acquires navigation signals independently with the hardware for an RAIM process. CONSTITUTION: Standardize residue values are determined from residues of the pseudo distances from the measured value. Sub sets(105,106) are determined(111). The sub set comprises the standardized residue values. The sub set having the smallest standard deviation is selected. Normal measured values(107) are selected.
