Study on High Sensitivity GPS Signal Acquisition Techniques Indoor Positioning
(0) GPS has been broadly applied in every fields of our social life, since the environment around us has been becoming more and more complicated, satellite navigation positioning technology with low SNR gains more and more attention. . 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 technologies, which is one of the difficulties on HS-GPS positioning technology are studied and analyzed in detail, 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.
