Document Type and Number:
WIPO Patent Application WO/2010/004873
Kind Code:
A1
Abstract:
Provided are an azimuth calculation device and an azimuth calculation method capable of preventing the azimuth from being displaced until the azimuth is stabilized. The azimuth calculation device is characterized by comprising an azimuth calculation means for calculating azimuth data from an output of a magnetic sensor, a buffer means for storing the azimuth data, and a control means for outputting the azimuth data when a predetermined number of pieces of azimuth data stored in the buffer manes are within a predetermined range.
