A positioning method, a tracker's terminal (13), a positioning arrangement and a computer software product for tracking an object (11a), such as a dog. The method uses GPS positioning. The GPS position information of the object (11a) is transmitted through either a circuit switched digital radio network (10b) or an analogue radio link to the tracker's terminal (13). The tracker's terminal includes a software application via which the received position information can, when desired, be transmitted though a packet switched network (10a) to at least one other tracker's terminal (22, 23).
