    • Systems and methods for navigation of a vehicle may carry out one or more operations including, but not limited to: obtaining coordinates of a vector connecting two points in space using carrier phase measurements from global navigation system satellites (GNSS); setting the vector as an intended path of a vehicle; storing carrier phase signals from a GNSS receiver received at a first position of the vehicle; receiving carrier phase signals from a GNSS receiver at a second position of the vehicle; and determining a position of the vehicle relative to the intended path from one or more carrier phase signals received at the second position and one or more stored carrier phase signals received at the first position.
    • 用于车辆导航的系统和方法可以执行一个或多个操作,包括但不限于:使用来自全球导航系统卫星(GNSS)的载波相位测量获得连接空间中的两个点的向量的坐标; 将矢量设置为车辆的预期路径; 存储来自在所述车辆的第一位置处接收的GNSS接收器的载波相位信号; 在车辆的第二位置处接收来自GNSS接收器的载波相位信号; 以及从在所述第二位置处接收的一个或多个载波相位信号和在所述第一位置处接收到的一个或多个存储的载波相位信号确定所述车辆相对于所述预期路径的位置。
