Abstract
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 information of current direction and send it to display module. This is the way how the invention proofreading the inaccurate direction.
