Title:
ATTITUDE REFERENCE APPARATUS
Document Type and Number:
Japanese Patent JP2014153106
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To solve the problem that a drift error cannot be accurately corrected if there is variation in delay time on a transmission line of a reference signal, when the drift error of a measured amount of an attitude reference apparatus is corrected using an accurate reference signal.SOLUTION: Using the property that the peak of a signal to be corrected and the peak of a reference signal must have essentially the same value even if the time relationship has ambiguity, the peak value of the signal to be corrected and the peak value of the reference signal are found, the difference between them is considered to be a drift error, and the difference is added to the signal to be corrected, thereby reducing the drift error.
