초록
This paper presents the PC based experimental software receiver which has been recently extended to a high bandwidth multiple frequency L1 signal for GPS and E1 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 L1 frequency band. © 2008 IEEE.
