A position estimation unit () comprising a first transceiver device () and a processing unit () that is arranged to repeatedly calculate time-of-flight (TOF) for radio signals (x, x, x, x, x, x) sent pair-wise between two transceivers among the first transceiver device () and at least two other transceiver devices (); calculate possible positions for the transceiver devices (), which results in possible positions for each transceiver device (); and perform Multidimensional scaling (MDS) calculation in order to obtain relative positions of the transceiver devices () in a present coordinate system. After two initial MDS calculations, between every two consecutive MDS calculations, the processing unit () is arranged to repeatedly perform a processing procedure comprising translation, scaling and rotation of present coordinate system such that a corrected present coordinate system is acquired. The processing procedure is arranged to determine the corrected present coordinate system such that a smallest change for the relative positions of the transceiver devices () between the consecutive MDS calculations is obtained.
