Rostselmash has started to equip combines with GPS auto-driving systems. The first combine ACROS 530 equipped with such system underwent tests and was demonstrated to journalists. Grain combine with “autopilot” may work on the field on a desired route with minimal operator's involvement. Automatic driving system consists of GPS receiver, direction indicator unit and steering assistance device. The system is presumed to be optionally installed on grain combines VECTOR, ACROS and TORUM. Possibility to operate on both GPS and GLONASS signals is being considered.
