Abstract

The invention relates to aircraft instrumentation, in particular to the production of induction magnetic heading sensors, and can be used in the manufacture of ferrozoid magnetometers. SUMMARY OF THE INVENTION: the method is based on the fact that the sensor is set to 0 ° when the vertical component of the Earth’s magnetic field (MRF) is compensated at the installation site due to the inclusion of a compensation magnetic field whose vector is equal in magnitude and opposite in direction to the vector of the vertical component of the MPZ, the compensation field is turned off, the error of the course formed by the sensor is recorded according to the following elimination of this error, and then repeat all the operations of leveling the ferry the ozond along the longitudinal axis of the suspension during the initial exposure of the sensor to the course 90 The device that implements this method contains an anti-magnetic rotary table 1 on which a custom sensor 2 is mounted and connected to the following magnetic course forming system 3, a solenoid 4, the longitudinal axis of which is oriented in space vertically; to create a magnetic field that compensates for the vector of the vertical component of the Earth’s magnetic field when the solenoid is connected to a stabilized current source 5. 2 s.p. f-ly, 1 ill. 9 00 00 С SL 00 00

The invention relates to the field of aeronautical instrument engineering, namely the production of induction magnetic heading sensors, and can be used in the production of flux-gate magnetometers.

The aim of the invention is to improve the accuracy of the sensor settings.

To achieve this goal, in the method of adjusting the magnetic field head induction sensor, which includes determining, with the help of the following system, the sensor errors from non-horizontal and horizontal gates of the flux gates by balancing the pendant suspension according to the appropriate axes to eliminate the found error, before determining the sensor errors from non-horizontal, the sensor set sequentially at the courses 0 ° and 90 ° while turning on the compensating magnetic field, the vector of which is equal in magnitude and opposite positioned in the direction of the vector of the vertical component of the Earth’s magnetic field, and determination of the error of the sensor from non-horizontalness is carried out in each of the positions for the corresponding flux gate after switching on the compensation magnetic field.

A solenoid and a stabilized constant current source are introduced into an induction sensor adjustment device comprising an anti-magnetic rotary table, a follow-up magnetic head forming system and a processing unit, the solenoid being connected to a stabilized constant current source and mounted perpendicular to the plane of the anti-magnetic rotary table.

The drawing shows a diagram of a device that implements the proposed method.

The device comprises an anti-magnetic rotary table 1, on which a custom sensor 2 is mounted, a follow-up system 3 for forming a magnetic course, a solenoid 4, the longitudinal axis of which is oriented vertically in space, and a stabilized current source 5.

The method is carried out as follows. Using the rotary table 1, the adjustable sensor 2 is set to the 0 ° course while the compensation magnetic field is turned on, the vector of which

equal in magnitude and opposite in direction to the vector of the vertical component of the MPZ, the compensation magnetic field is turned off and according to the readings of the system 3

course formation determines the error from the non-horizontal horizontal transverse probe.

This error is eliminated by balancing the pendulum suspension along its axis.

Then, all the operations of horizontal alignment of the flux-gate along the longitudinal axis of the suspension are repeated at the initial exposure of the sensor to a course of 90 °.
