Abstract

PURPOSE:To enable to easily read the direction to be corrected and a correction angle, by a device wherein the travelling course toward the destination is preset and a deviation in course from the preset course is indicated. CONSTITUTION:A pulse signal induced in an output winding of a flux gas magnetic sensor 1 is amplified by an amplifier 2 and then integrated by an integrator 3. Output from the integrator 3 includes two course components obtained by rectifying the pulse signal which has a peak value in accordance with the course represented in the output from the output winding of the magnetic sensor 1. A converter 4 outputs digital signals corresponding to those course components. Based upon the digital signals from the converter 4, whose signal corresponds to the current travelling direction, and a digital signal from a travelling course selecting device 5, whose signal corresponds to the course preset in alignment with a route toward the destination, an arithmetic processing unit 6 calculates a deviation angle in the current travelling course from the course preset by the current course electing device 5 and then thus calculated deviation angle is displayed on an indicator 7.
