Software Receiver Design for Galileo Signals

The article presents a new concept of softwarebased GNSS receivers because of its advantages in flexibility and possibility of reconfiguration. The aim is to develop a receiver for navigation signals of the Galileo system testbed, the Giove-A and Giove-B. The receiver must be able to acquire, track and demodulate signals "BOC" system. For this test different techniques, both in the acquisition and follow-up. Also developed a configurable signal generator for testing and a graphical user interface to manage the receiver easily. The results show that the signals can be acquired successfully with a front-end narrowband GPS and conventional algorithms. Similarly, you can track and demodulate the data channel signal (E1B) using the BOCPRN configuration.
