Abstract

Global Position System is more and more close with people's life from start run till now. It has already been applied to various fields. Compared with the common circumstance, as outdoors, GPS signals power will be weaken much. So researches on HS-GPS indoor position technology are necessary in the extreme to implement high accuracy position in indoor environment. Weak GPS signals acquisition algorithm in low signal to noise ratio environment is studied, signals process flow and acquisition performance of algorithm, such as coherent integration, non-coherent integration and differentially-coherent integration. It can be seen from theoretical analysis and simulation that differentially-coherent integration is capable of detecting GPS signals in low signal to noise ratio environment. [ABSTRACT FROM AUTHOR]
