摘要
本文阐述了几种GPS手机定位系统的工作原理,并分析它们定位时的能耗情况,指出智能中间插件由于其较高的性能/功耗比在低功耗手机定位系统中扮演重要角色。不断降低功耗将推动手机定位的普及和定位服务的发展。
This paper elaborates the operating principles of several location systems of GPS mobile phone and analyses the power consumption during their location operation. It points out that the intelligent middleware layer plays an important role in the location systems of mobile phone with low power consumption because of the relative higher ratio of capability/power consumption. Reducing the power consumption constantly will promote the popularization of location systems of mobile phone and the development of location service.
