MAGNETIC COMPASS Russian patent published in 2007 - IPC G01C17/30 

FIELD: the invention refers to the field of navigational instrument-making industry.

SUBSTANCE: the arrangement has a pendulum sensor with two orthogonally-oriented flux gate meters. Each output of the flux gate meters is connected through corresponding amplifying-transforming blocks with an input of a numerical calculator. Additionally there are in the arrangement two circuits of cascade connection of a switchboard and a scaled resistor. The input of the and the second circuits is switched correspondingly to the output of the first and the second amplifying-transforming blocks. The output of the first and the second circuits is switched correspondingly to the input of the winding of the second and the first of the flux gate meters. At that the output of one circuit is switched to direct input of the winding and the output of another circuit - to an inverting input of the winding. At that the outputs of the control of the switchboards are switched to the output of the numerical calculator.

EFFECT: increases reliability of autonomous automatic control of proper functional work.
