FIELD: instrument making.
SUBSTANCE: invention is related to magnetic measurements on moving objects, in particular to instruments intended for measurement of components and complete vector of Earth magnetic field induction, and also to magnetic course indication and navigation in transport means. Device comprises serially connected and mutually closely located three-component detector of magnetic field, which is rigidly connected to axes of object, and transceiving device installed in fixed position on object, which includes serially connected commutator, analog memorising device, unit of analog-digital conversion and microcomputer.
EFFECT: higher accuracy of magnetic measurements on moving object by elimination of electromagnetic noise effect from transceiving device of magnetic-measurement instrument.
