Abstract
The invention relates to a method for performing positioning, in which a spread spectrum signal modulated with a repetition code and transmitted by satellites, is received. The method comprises the steps of acquiring the received, spread spectrum modulated signal, measuring the code phase of the received, spread spectrum modulated signal, and receiving the Ephemeris parameters of satellites which are used in the positioning. Furthermore, in the method, said code phase measurement results are stored, which have been measured at least partly before receiving the Ephemeris parameters, wherein the stored measurement results are used in the positioning after the Ephemeris parameters have been received.
