This course will deal with the more advanced aspects of Global Navigation Satellite System (GNSS) receiver design. GNSS receivers considered will be those that can track signals from GPS both current and modernized constellations, GLONASS and Galileo. Initially, GNSS positioning is introduced for those who have not completed GMAT9201. The remaining topics will likely vary from year to year to ensure new developments are incorporated into the teaching, but will typically include: specifications for the GPS L2C and L5, GLONASS and Galileo signals, frequency plan implications of the new GNSS signals, correlator implications of the new GNSS signals, antenna design challenges, time transfer, integrity and RAIM, weak signal GPS assisted GPS (A-GPS), integration with inertial systems and Software Radio basics. These principles will be illustrated using Matlab-based exercises and working receiver development kits.
