20810268-1 - LOCALIZATION AND NAVIGATION SYSTEMS

To acquire general concept on new generation mobile networks (3G, 4G, 5G, 6G) as part of a communication system. To provide an overview on main operating principles of a structured mobile network, such as the available services also from a financial and economic viewpoint, quality requirements, mobility management, security, secrecy and authentication problems, localization services, power control of connected devices, access technologies from wireless devices, evolution of architecture of SW network virtualization, algorithms of array processing to allow dedicated efficient links in modern standards (5G and beyond) between terminals or smart objects connected to the IoT world.

Programme

Part I: GNSS fundamentals
- GNSS Architecture: GNSS segments, GNSS signals (GPS, GLONASS, Galileo, BEIDOU).
- GNSS time Reference, coordinate frames, satellite orbits and coordinates computation.
- GNSS Measurements: measurement modelling, atmospheric effects, combination of GNSS measurements.
- Navigation equations, code-based positioning, carrier-based positioning, positioning algorithms.

Part II: GNSS receivers
- Requirements, architectures and designs.
- GNSS signal acquisition and tracking.
- Software-defined GNSS receivers.

Part III: advanced GNSS techniques
- Augmentation systems
- Real-time Kinematics (RTK)
- Precise Point Positioning (PPP): LAMBDA method.
- Kalman filtering

Part IV: Heterogeneous systems
- Inertial sensors, Inertial Navigation Systems (INS), navigation equations
- INS/GNSS integration: loosely-coupled and tightly-coupled INS/GNSS integration.
- Visual-based navigation (camera, LIDAR), Visual-inertial odometry, Simultaneous Localization and Mapping (SLAM).
- terrestrial radio-localization systems based on 4G and 5G mobile networks, and local area networks (WiFi, Bluetooth, ZigBee, UWB, RF-ID, etc.)

Laboratory exercises throughout the course provide the necessary background for going further into the theoretical concepts and their practical implementation.
