Study on GPS L1 and Galileo E1&E5a Signal processing implementation of Hybrid GNSS Receiver & its verification with live signal

The Hybrid GNSS Receiver consisted of H/W Antenna. RF/IF units and SW Signal Processing Unit to cover the GPS and Galileo signals. The receiver can process wide-bandwidth multiple frequency L1/L5 signal for GPS and Galilee E1/E5a signal. we gathered GIOYE-B Signal by using H/W Antenna and RF/IF units in IF-level as sampling frequency and bit number. 112MHz and 8bits, respectively. Data acquisition was done by using commercial data acquisition device from National Instrument" The gathered data was fed into SW receiver to process GPS L1 and Galileo Eland E5a. We had processed GIOVE-B signal and the performance of the receiver was check with values of C/N0. The signal acquisition and tracking results were satisfactory and the performance of the prototyped receiver units was successfully carried out.
