GEAR FOR DETERMINATION OF ANGLE OF TURN Russian patent published in 1996 - IPC

FIELD: measurement technology. SUBSTANCE: invention may be used to determine mutual spatial orientation of objects. Gear for determination of angle of turn includes three-component magnetometer put on mobile object and computer of angle of turn. Gear is supplemented with system for formation of alternating reciprocally orthogonal magnetic field manufactured in the form of two pairs of flat closed circuits arranged in symmetry relative to center of rotation of mobile object and magnetometer and three-channel matching unit. Each channel of its is composed of two parallel circuits including filter and meter of value of signal of magnetometer connected in series. In addition to this each of interconnected closed circuits is linked to A.C. generator. One of them uses frequency f₁ and the other one - frequency f₂,. Filters included into each channel of matching unit are tuned to these frequencies. Outputs of all meters of value of signal of magnetometer are connected to inputs of angle of turn which determines present angle of turn of mobile object and magnetometer. EFFECT: increased accuracy of measurement when used in complex mobile systems. 1 tbl
