t and the currently generated replica code sequence u03b8 t is zero an error value of zero corresponds to the center point of a correlation function at which the output of a correlator has its maximum value the adaptive loop filter 24 provides an indication in which direction and by which amount the phase of the generated replica code sequence should be adjusted in order to reduce the phase error based on the indication provided by the adaptive loop filter 24 the additive integrator 25 computes a new frequency value for the prn generator 26 the prn generator 26 then creates the desired replica signal u03b8 t with a frequency defined by the additive integrator 25 the additive integrator 25 will thus only change the frequency of the generated replica code sequence but with the frequency errors of the frequency and the phase of the replica code sequence can be corrected the replica code sequence u03b8 t generated by the prn generator 26 is provided on the one hand to the comparing component 21 in order to enable a continuous tracking on the other hand the generated replica code sequence u03b8 t is provided at the output u201c out u201d of the tracking loop 13 for further use to processing component 14 e g for enabling a decoding of the received sky signal u03c8 t for positioning purposes the adaptive loop filter 24 may further comprise a decision function which determines whether the measurement values provided by the discriminator 23 are too far away from the zero value for a pull in even with the enlarged effective control range in case it is decided that the measurement values are too far away from the zero value a re acquisition or new acquisition of the.
