The currently available tracking technique in GNSS-SDR includes three parameters(code phase, Doppler shift, carrier phase). The GNSS-SDR technique however has certain limitations regarding the filtering of weak signals.
The project will be executed using GNSS-SDR along with the equations of KF filter. Another parameter will be added to the existing tracking method and it will be tested using sample and raw signals. The results are compared with those obtained from traditional techniques.
