This chapter provides a review of existing experimental and professional Galileo receivers, related application projects and selected design topics, such as generic tracking channels, fast acquisition algorithms and AltBOC tracking. Although at the time of writing Galileo as a GNSS system is not yet fully deployed, quite a number of Galileo receivers have already been created with the help of Galileo simulators, mainly in the context of European projects, the most significant being the Galileo Test User Receiver project (TUR). Some Galileo receivers have also been developed to test the signals of experimental Galileo satellites GIOVE-A/B.
