VT 2014
Satellite geodesy is the most
quickly growing discipline of geodesy, providing methods that are increasingly used
in geodesy, surveying, engineering, geophysics and related fields. This course
gives a general theoretical background and practical application of satellite
positioning, in particular to the Global Positioning System (GPS). Other
systems discussed in the course are the Russian satellite navigation system
GLONASS and the future European satellite system Galileo, etc. The course also
gives an orientation of other satellite methods used in geodesy, e.g. for the
determination of the Earth’s gravity field.
