1. A method comprising:
- assembling, by an apparatus, messages including measurements on satellite signals that are valid for a reference station and explicitly including for a respective measurement instant for which measurements are included an indication of a current movement of the reference station, said indication being determined independently of measurements on satellite signals; and
providing, by the apparatus, the assembled message for transmission to a device.

Abstract
For enhancing the quality of a relative positioning, a filter is adjusted depending on information on a movement of a satellite signal receiver. A position of the satellite signal receiver is determined relative to a reference station using the filter, wherein measurements on satellite signals received by the satellite signal receiver and measurements on satellite signals provided for the reference station are used as input to the filter. The measurements for the reference station may be received in messages which are assembled and provided for transmission and which may include in addition an indication of a current movement of the reference station.
