1. An apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code being configured to, with the at least one processor, cause the apparatus at least to:
receive information on a path to be followed by a drilling rig, the path including a trigger position for selecting a reference point associated with the drilling rig;
determine a position of the drilling rig;
instruct the drilling rig to follow the path based on a first reference point associated with the drilling rig, a position of the first reference point being considered as a position of the drilling rig by a position control algorithm controlling movement of the drilling rig;
activate, in response to determining that the position of the drilling rig corresponds to the trigger position, a second reference point associated with the drilling rig, a position of the second reference point being considered as the position of the drilling rig by the position control algorithm controlling movement of the drilling rig; and
instruct the drilling rig to stop in response to determining that the position of the second reference point corresponds to a target position for performing an operation using the drilling rig, while the drilling rig is so positioned at the second reference point.
