    • Methods and systems for measuring coordinates of a target, particularly under strong multipath conditions, are described. A satellite navigation system antenna (105) and a tilt sensor (130) are mounted on a range pole (120), with the sensor at the pole's bottom tip. Signals from the antenna and tilt sensor are provided to a receiver (107), which computes the antenna's coordinates from the antenna signals, and the pole tips position from the computed coordinates and the tilt data. The operator places the pole tip on the target and swings the pole by hand over an angle sector of 15 degrees while keeping the tip on the target. Height of the target can be computed with a single measurement set, and X-Y coordinates with just three measurement sets. The use of additional measurements reduces errors in the target's coordinates since multipath errors are uncorrelated during movement of the antenna. Vertical alignment of the pole is unnecessary.
    • 描述了用于测量目标的坐标的方法和系统,特别是在强多径条件下。 卫星导航系统天线(105)和倾斜传感器(130)安装在距离极(120)上,传感器位于极底部。 来自天线和倾斜传感器的信号被提供给接收机(107),其从天线信号计算天线的坐标,并从所计算的坐标和倾斜数据计算极点位置。 操作者将极尖放置在目标上,并用手将杆倾斜15度的角度,同时将尖端保持在目标上。 目标的高度可以用单个测量集来计算,而X-Y坐标只有三个测量集。 使用额外的测量可减少目标坐标系中的误差,因为天线移动期间多径误差不相关。 极的垂直对齐是不必要的。
