Abstract
A method and a software product for positioning a drilling unit in a rock drilling rig, and a rock drilling rig. The drilling unit (5) included in the rock drilling rig (1) is manually displaced towards a starting point (14) of a hole (19) to be drilled next. A control unit (11) in the rock drilling rig (1) performs after the manual displacement (A) an automatic positioning (B) accurately to the starting point in order to initiate drilling.
