DEVICE FOR DETERMINING COORDINATES OF A MOBILE OBJECT USING A MAGNETIC FIELD Russian patent published in 2020 - IPC G01S5/16 G01R33/02 G01V3/10 

FIELD: measuring equipment.

SUBSTANCE: invention relates to the field of measurement equipment, in particular to the mobile object coordinates determining means, and can be used in landing systems of aircrafts, in construction for directed drilling of wells, in navigation systems of mobile objects, in medicine for precision positioning and other fields of science and technology. Technical result is achieved due to that in device for determining coordinates of mobile object in ground equipment additionally introduced in series connected control unit and first key circuit, which output is connected to second inductance coil, harmonic signal source output is connected to second input of first key circuit, on-board hardware includes series-connected ground equipment operation mode determination unit, second key circuit and reference signal generator, output of which is connected to second input of phase difference determining unit, as well as the third and fourth key circuits, the first inputs of which are combined with the input of the ground equipment operation mode determination unit and the second key circuit second input and are connected to the measuring device output, second output of unit for determination of operating mode of ground equipment is connected to combined inputs of third and fourth key circuits, outputs of third and fourth key circuits are connected to input of unit of amplitude measurement and second input of unit for measuring phase difference.

EFFECT: broader functional capabilities of the device, particularly navigation for a remote mobile object.
