1. the method for the location database for optimum position system, substantially position is stored in the location database and is fixedTransmitter reference by location, wherein, the reference by location be used to position, wherein, in a first step,Determine to pass by by means of a positioning device by the radio signal of the fixed transmitter in substantially position the one of distanceFirst position sequence (12),By coupling a second position is determined by other sensing datas of the inertial navigation system (INS) of the positioning deviceSequence (14),Wherein, in a second step (20),First position sequence (12) and second position sequence (14) are compared to each other,Wherein, based on estimation, i.e., the path determined by the inertial navigation system (INS) by the second position sequence (14)It is more accurate than passing through the first position sequence (12) that the alignment system determines, determine the error of the alignment system, that is, be used forError (the E of the position of First ray (12)i),Wherein, it is based on corresponding error (E for each position of First ray (12)i) determine, the variation pair of the location databaseThe position (12) it is determining have what influence andWherein, the amendment to the location database is carried out based on the influence.
