装置。[Claims for Utility Model Registration] 1. An excitation winding wound around an annular magnetic core placed in the earth's magnetism, and two sets of output windings wound so as to surround mutually orthogonal portions of the magnetic core and orthogonal to each other. The two-component detection signals obtained from the azimuth detection sensor and the output winding are respectively detected and integrated, and then amplified by amplifiers each having a different reference voltage to create a two-component azimuth analog output. , a direction detecting device comprising a means for calculating a direction based on the output and specifying a specific direction, takes in the analog output of the two components, determines whether the output is saturated or unsaturated, and based on the result, calculates the direction and specifies the specific direction.
An azimuth detection device characterized by comprising a correction section that changes the reference voltage of each amplifier of the set so that the output voltage that changes in synchronization with the reference voltage of the amplifier falls within an unsaturated region. 2 In paragraph 1 of the claims for utility model registration, the correction unit digitizes the azimuth two-component analog output using an A/D converter, performs arithmetic processing on a microcomputer, and then converts the arithmetic result into a tenalog using a D/A converter. A direction detection device characterized by having a voltage output of .
