N2 - In this paper an implementation, verification and test results of MLE based Doppler frequency tracking method, so called F-correlator, are presented for multi-frequency GNSS signal trackings. Direct use of MLE-based F-correlator method to the received signal model is based on a new cost function for carrier Doppler tracking and makes it possible to use a various kind of estimation techniques. The MLE solutions both for code delay and carrier phase contain only a computation of normal form of baseband I and 0 values while that for Doppler frequency requires a computation of time index k inside of coherent integration and dump process, thereby producing a different form of baseband I and Q values. Test results show that the MLE algorithms in this paper provided a superior performance to the conventional method specially in high dynamic cases.
