A Software Receiver Implementation for GPS L1 and Galileo E1 Signal

This paper presents the PC based experimental software receiver which has been recently extended to a high bandwidth multiple frequency LI signal for GPS and El signal software receiver. The presentation briefly touches upon on signal tracking using prototyping hardware antenna, RF-IF section and software baseband section. In this paper, the efficient algorithms are developed about the signal acquisition and tracking parts in order to obtain the accuracy pseudorange. Finally, the pseudorange is calculated through the relative channel delay received through the different satellite of LI frequency band.
