ABSTRACT:
The invention relates to a method and arrangement for improving the accuracy of time measurements related to positioning in a radio system. In the method, a test signal is generated; the test signal is directed to travel through pre-selected radio frequency parts of a receiver used in positioning in the radio system; the propagation delay of the test signal through the pre-selected radio frequency parts is determined; and the determined propagation delay is used to improve the accuracy of time measurement related to positioning.
