Abstract
A method for performing reacquisition in a positioning receiver (PR) is described, in which at least one spread spectrum modulated signal is received. In the positioning receiver (PR), a reference signal is formed by using a reference code corresponding to the code used in the modulation of the signal to be received, and a correlation is made between the received signal and the reference signal. The correlation is made in at least a first and a second part, and different correlation times are used in the first part and in the second part. The invention also relates to an electronic device (ED) comprising a positioning receiver (PR) for performing this reacquisition method.
