Abstract
GNSS (Global Navigation Satellites System) is the general meaning of the satellites-based navigation system. The available two satellite systems include GPS (Global Positioning System) in the United States and GLONASS (Global Navigation) in the Russia right now; and other system, Galileo which is developed by EU (European Commission) and ESA (European Space Agency) will be set up well in 2008.
The Galileo satellite system has some following characteristics. It is different from United States and Russia navigation satellite system which aims military purpose object originally. It is mainly for civilian use worldwide. Galileo can provide a highly accurate, guarantee global positioning service under civilian control. It will be inter-operable with GPS and GLONASS, the two other global satellite navigation systems.
In this thesis, an analog front end receiver architecture is presented to receive GPS and Galileo satellite signals simultaneously. Furthermore, the design and analysis of the complex filter, the non-ideal effects of the frequency synthesizer and the algorithm of the AGC (Automatic Gain Control) are also discussed.
