This course introduces the electronic and signal processing aspects of Global Positioning System (GPS) and other satellite navigation systems e.g. Galileo, GLONASS. The following topics are covered in the course: signal specifications for GPS L1, L2C and L5, GLONASS and Galileo signals, introduction to CDMA, frequency plan implications of the new GNSS signals, calculating a position, problems receiver designers must overcome (multipath, interference etc.), front-end RF design, correlator principles and approaches, signal acquisition/reacquisition, how measurements are made, receiver interfaces, augmentation systems (e.g. EGNOS, WAAS), Software Radio, weak signal and Assisted GPS and Interference. These principles will be illustrated using Matlab, allowing students to develop algorithm components of receivers.
