Course unit contents: 'Satellite Navigation' is a 9 credit course offered to students of the second year of 'Laurea Specialistica' in Aerospace Engineering. The course includes theoretical background and practice in developing simple applications in data processing.
Planned learning activities and teaching methods:  Understanding coordinates, coordinate systems, least squares.
 The propagation of microwaves through the ionosphere and troposphere. Multipath.
 Architecture of a GNSS: the Space Segment, the Control Segment and the User Segment. GPS vs. GLONASS vs. Galileo: code, phase and navigation message. The Time To First Fix. Assisted GPS. EGNOS and WAAS.
 How to compute the coordinates and clock offsets of the GNSS satellites from broadcast ephemeris or postprocessed products.
 The pseudorange data and how to invert them to estimate user coordinates and their accuracy.
 Tracking user coordinates in time: The state transition matrix; epochwise estimates by least squares vs. filtering. Kalman filter formulation. Estimation of coordinates, velocity and acceleration. Inclusion of stochastic error models into the filter.
 How to pack everything into a product: a Google Earth navigator vs. a navigator based on vector cartography.
