Abstract: The present invention relates to methods and apparatuses as well as a measurement report signal for reporting measurements on ranging signals (RS1-RS4) received by a mobile station from satellites (SV1-SV4) or calculating a position based on such measurements, wherein each of said ranging signal comprises a stream (201) of data bits (202) spread by a spreading code (203). After synchronizing (501) to data bit edges in the stream of data bits on a ranging signal, a position in time modulo the data bit length for said stream of data bits with respect to a selected point in time is measured (502). The measured position in time could be used by the apparatus performing the measurements on the received ranging signals for calculating (504) the position of the mobile station. Alternatively the apparatus could transmit (503) a wireless signal including data representing said measured position in time, allowing the mobile station position to be determined in another apparatus (101).
