UNIAXIAL STAND FOR EVALUATING THE FREQUENCY RESPONSE FUNCTION OF THE MAGNETIC COMPASS CORRECTION SYSTEM Russian patent published in 2021 - IPC G01M1/00 

FIELD: instrumentation.

SUBSTANCE: invention relates to instrumentation field. Uniaxial stand for evaluating the frequency response function (FRF) of the magnetic compass (MC) correction system is characterized by the fact that the axis of MC cartouche rotation is located on lever against the platform rotation axis in such a way that when the platform is rotated, the bowl approaches to one of two permanent magnets, each of which is fixed motionless and applies an additional magnetic moment to MC cartouche magnetic system, which leads to its additional turn proportional to rolling motion tolerance. According to information from stand angle sensor and MC cartouche angle sensor in yaw mode at set frequencies, FRF correction system is calculated to compensate the additional MC error caused by pitching.

EFFECT: assessment of suppression degree of MC additional tolerance caused by yawing of the object with different frequencies using MC correction system characterized by its frequency response.
