Need of robotization of the self-propelled farm vehicles and machine-tractor aggregates (MTA), providing performance of field work without participation of people, demands development of tool methods and creation of hardware components of programming of mechanical trajectories of MTA on working run. In the article is considered the solution of this task by aids of the variation magnetic fields created by currents of wires of stationary navigation inductors.
There was offered the classification of induction methods of MTA positioning by the form of the main signs. It is shown that the program of the movement depends on type of the inductor, type of primary navigation parameter, algorithm of the actual value and way of task of planned value of the secondary navigation parameter. It is established that when using non-switchable inductors it is reasonable to feed adjacent run wires with counter currents, as primary parameter to use strength vector projection to transverse axle of the tractor and to determine location of MTA by two-point amplitude-difference method. During MTA positioning by amplitude-phase method on electric-field vector projection to Z-axis it is reasonable to create magnetic field by the "double loop" of the inductor, which is created by "multibeam star" inductor wires commutation.
