- 基于无线移动通信网络的定位是以获取用户手持终端(包括手机或者平板等设备)的位置为目标。而达成这一目标的手段是通过测量无线电信号的强度、传播时间、到达角等物理指标,并将其转化成终端与基站之间的距离、角度等信息,最终利用定位算法将距离、角度等信息转化成终端的坐标信息。 虽然商用GPS已经随着智能手机的发展而得到了广泛的应用,但是,在诸如室内、地下、高楼林立的市区等诸多场景中,GPS定位性能较差。由于在覆盖广度和深度上,基于无线网络基站的定位系统相比GPS存在优势,因此,越来越得到运营商和新兴创业

RTKlib关于高精度GPS动态定位函数与处理过程整理
- 精密GPS动态测量采用载波相位差分技术,其标准测量模式为,一台GPS接收机置于已知点,作为基准站来进行静态测量,另一台GPS接收机置于载体上,作为流动站来进行动态测量。两台接收机同步观测相同的卫星,然后将两台GPS接收机的观测值进行组合处理,就可以获得流动站相对于基准站的坐标和速度。本文主要介绍用RTKLIB 实现精密动态定位的过程,该过程包括观测文件和导航文件的读取、基准站位置的计算、流动站位置的求解、运行结果的输出,下面将分块讨论。(Precision GPS dynamic measure
