1. A method of calculating a position fix from satellite signal samples, the method comprising:

  • obtaining first reference information produced during the calculation (120a) of a first position fix, the first position fix being the calculated position of a satellite-positioning receiver (5) at a first time;

    obtaining second reference information produced during the calculation (120b) of a second position fix, the second position fix being the calculated position of the receiver (5) at a second time;

    receiving a set of satellite signal samples generated by the receiver at a third time, or ranging measurements derived from such a set of satellite signal samples; and

    processing (140) the set of samples or the ranging measurements to calculate a third position fix,wherein said processing (140) is assisted by the reference information produced during the calculation of the first and second position fixes.
