METHOD OF DETERMINING DIRECTION OF GEOGRAPHIC NORTH USING MOLECULAR-ELECTRONIC ANGULAR SPEED SENSOR AND INCLINATION ANGLE SENSOR Russian patent published in 2016 - IPC G01P15/08 G01C17/00 

FIELD: geography.

SUBSTANCE: invention relates to navigation devices, in particular can be used for determining direction of geographic north. Technical result is achieved due to that device for determining direction of geographic north, includes in addition to sensor of angular motion sensor which is sensitive to change angle of inclination. Signal processing is performed by elimination of angular motion sensor signal signals caused by slopes rotation axis, using readings of installed on same platform sensor which is sensitive to changes in inclination angle. At beginning of platform rotation is determined based on stabilisation of electrode current fixed molecular-electronic sensor. To reduce time of stabilisation of electrode current preliminary mechanically mixed fluid in angular velocity sensor by vibration platform or is placed in liquid outside region where transforming element angular velocity sensor additional electrodes located at same electric potential.

EFFECT: high accuracy of determining direction of geographic north.
