A Real Time High Sensitive Software GPS Receiver Architecture and Verification

Y. Liu, T. Jin, H. Qin

Abstract:	This paper mainly provides a prototype of high sensitive software GPS receiver architecture and its verification under different environments. Software radio defined (SDR) platform was firstly introduced, and then detailed schemes were discussed in accordance to modules in the receiver. Signal acquisition algorithm was analyzed based on the coherent correlation and non-coherent accumulation detector; signal tracking algorithm was analyzed in low and high dynamic environments separately; cross correlation effect has been also taken into account when strong and weak signal coexisted. In summary an overall high sensitive receiver performance overflow was designed and implemented in a PC based software platform. Finally experimental verification has been done with both simulation and real environment separately.
