APPARATUS FOR MONITORING SYSTEM TIME DIFFERENCES OF GLOBAL NAVIGATION SATELITE SYSTEM(GNSS) AND METHOD FOR CONTROLLING THEREOF

摘要

The present invention relates to an apparatus for monitoring system time differences of a GNSS and a control method thereof. In a method in which a multi global navigation satellite system (multi-GNSS) using a plurality of satellite position measuring systems related with one embodiment of the present invention monitors time differences of each of the plurality of satellite positioning systems. The method of the present invention may include: a first step of setting a first station in the multi-GNSS as a reference station; a second step in which the reference station transmits first time information to a second station most adjacent to the reference station; a third step of judging whether the second station is a final station or not; and a fourth step of calculating time difference of each of the plurality of satellite position measuring systems using the first time information if the second station is the final station, and setting the second station as the reference station newly if the second station is not the final station. [Reference numerals] (AA) START; (BB) END; (S410) Step of setting first station on link as reference station; (S420) Step of transmitting time information to most adjacent unused station from reference station; (S430) Step of setting destination station as new reference station; (S440) Whether arrives at final station; (S450) Step of summing all time transmission results to acquire time difference solution
