| Abstract: | The progress in High-Sensitivity GPS(HSGPS) technique is introduced in this paper;the application prospect and research signification of HSGPS technique are indicated.The signal characteristic of environments,unlike that of conventional GPS,such as indoor,foliage and urban is analyzed;the theory of HSGPS technique is reviewed.Acquisition of weak indoor GPS signals is the most important part in HSGPS technique,the methods for acquisition of weak indoor GPS signals are recommended in detail and the characteristic of those acquisition algorithms is summarized. |
