全球导航卫星系统定位技术-辅助性系统是在传统卫星定位的基础上进行扩充，将无线网络技术运用在上面与之结合，有无线网络技术的各种优点。辅助系统数据大大缩短了定位所需的时间，即使是在信号非常弱的地方依然可以定位，另外它还使传感器的灵敏度大大提高。但该辅助系统还存在着一定缺陷，它必须满足特定的观测条件才能使用，一旦这些条件不符合，就无法进行定位。所以如何通过其他路径来满足定位的条件，成为辅助系统定位技术成功的关键，文章就该项技术进行深入剖析。

GNSS positioning technology-supporting system, which is based on the traditional expansion of satellite positioning, based on the wireless network technology used in conjunction with the above, there are various advantages of wireless network technology. Auxiliary system data greatly reduces the time required for positioning, even still very weak signal may be positioned in place, and it also greatly improves the sensitivity of the sensor. However, the auxiliary system, there are still some defects, it must meet certain conditions in order to use observation, once these conditions are not met, it is impossible to locate. So how to locate other paths to meet the conditions to become a successful critical auxiliary system positioning technology,the paper-depth analysis on the technology.
