Method for compensating asynchronous error of trapping gyro

PURPOSE: An asynchronous error compensation method of a trapping gyro is provided to remove posture errors and position errors due to asynchronous gyro output generated in an existing navigation system. CONSTITUTION: An asynchronous error compensation method of a trapping gyro comprises the following steps. Data buffer sets are produced, and gyro data from a specific trapping gyro is saved successively(S10). If valid data exists, search is performed from the existing point of the valid data to the existing point of new valid data(S60). The count value from the valid data to the new valid data is saved(S70). The partitioned data is calculated(S80).
