摘要
介绍了高灵敏度GPS(High-Sensitivity GPS)技术的研究进展及高灵敏度GPS技术的应用前景和研究意义。分析了GPS信号在室内、森林、城市等一般GPS接收机无法应用环境的特性,综述了高灵敏度GPS关键技术的基本原理。高灵敏度GPS技术的核心就是室内环境微弱GPS信号的捕获技术,重点介绍了捕获室内环境弱GPS信号的基本方法,总结了各种捕获算法的特点。
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.
