This invention discloses a method and setting to proofread the direction of global position system. This invention at least includes the parts as follow: a central processor, a global position signal incepting module, a numeral magnetic drag feeler search and a procedure control module. To put the method into effect, first, take over the global position signal through a global position signal incepting module and pass it to the central processor; the central processor estimates whether the signal is effective or not by the procedure control module; If the conclusion is 'yes', the procedure control module will identify whether the current speed is smaller than the speed limit preinstalled based on the global position signal; If the conclusion is 'yes' as well, a numeral magnetic drag feeler search will detect the current position and get a set of numeral direction signal, then pass it to the central processor; Finally, according to those numeral direction signals, the central processor chalk up the proofreaded
