FIELD: measuring equipment; calibration.
SUBSTANCE: invention relates to measurement carried out by a global navigation satellite system (GNSS) receiver, particularly to a method for automatic calibration of an angle sensor for an automatic control system for automatic drive of agricultural machines. Method of automatic calibration of angle sensor for control system of automatic drive of agricultural machine includes several stages. Steering wheel car is fixed to hold the front wheels of the vehicle. Then information on current position of machine is collected and processed to obtain average value. A kinematic model of a two-wheeled agricultural machine based on the center of the rear axle is created. A radius is calculated to obtain a set of correlations of angles. Machine is rotated by preset angle at constant speed, with rear axle of machine as center. After repeated execution of the previous step, the angle is calculated by selection to obtain a calibration factor.
EFFECT: higher accuracy.
