Abstract
The invention relates to a device and to a method for determining the position for a working part of a tool on a working machine. A position determining apparatus is placed in a defined position on the working machine in order to determine the position of this place in a coordinate system fixed in space. The position-determining apparatus comprises partly a relatively slow determining device ( ), which at time intervals measures the actual position of the machine , and partly a relatively fast determining device ( ; ACC , ACC ) which reacts on position changes of the machine in order to calculate and up date the determination between the said time intervals.
