GNSS出现，无需垂直平整杆位吗？

用GNSS天线出发是一项棘手的任务。查看控制器屏幕上的说明和值，将杆移至所需位置，并通过将杆气泡居中（全部同时）确保垂直于垂直的位置 - 需要仔细执行，并且不容易，尤其是当时间压力为高的。与新的Leica GS18 t, setting out is much more convenient and faster than ever before. In this article Paul Dainty explains more.

Surveyors and setting out engineers are no different. Pressure at work is high. There are the usual time-critical tasks to do on a typical construction site such as checking the as-built structure, or setting out earthworks or building foundations.

压力打开。船员和一台昂贵的机器正在等待.

但是有时候，现场压力可能会变得很高。想象一下，挖掘机机器刚刚到达现场的时间比计划的要早到现场，并且已经准备好开始土方工程了。问题是尚未列出配置文件，这需要在土方工程开始之前进行。设置工程师是唯一可以做到这一点的人。压力打开。当然，他现在必须尽快将这些个人资料板设置为最高的准确性，而一台非常昂贵的机器正在等待闲置，甚至不提及数十名不耐烦的工人。

使用传统的GNSS RTK漫游者出发可能很慢

With a conventional GNSS RTK rover, setting out is a rather slow and methodical procedure. This is because the pole needs to be held vertically at the same time as looking at the setting out information on the controller screen all the while moving the pole into position. The GNSS position is calculated to the antenna, which is fixed onto a 1.8 m or 2 m pole. Hence, for the setting out information on the screen to be correct, the pole must be held vertically by centering the pole bubble.

To set out a position accurately, it is needed to perform several tasks at the same time:

• Look at the setting out instructions and values on the controller screen
• Walk and orientate: Move the pole to the required position so that the stake values are close to zero
• Ensure the pole is vertical by centering the pole bubble

用新的Leica GS18 T进行了简化的设置。看着杆气泡并握住杆垂直（如图像中）是历史记录。

As it is extremely difficult to do these all at the same time, it is generally preferred to follow those tasks in an iterative process:

It needs to be an iterative process because by centering the bubble to ensure the pole is vertical in step 3, we probably need to move the antenna, and need to go to step 1 again to check the setting out instructions on the screen. Then do step 2 again to adjust the pole position, and so on. To set out a position accurately enough, the process probably has to be performed two or three times, which is not particularly difficult, but it does take time to do it properly.

Now returning to our site, imagine the excavator and the crew of workers waiting for you to carefully set out the profile boards, performing the iterative setting out process on each one. The situation is likely to be very stressful and mistakes are likely to happen, slowing the process down further.

想象一下能够出发而无需执行此迭代过程。

好吧，现在可以使用Leica GS18 twith tilt compensation. The GS18 T is the first GNSS RTK rover to allow staking out with a tilted pole. Because the GS18 T combines seamlessly with theLeica Captivate在软件中的任何应用中，都可以实地软件，倾斜补偿测量。我们可以用倾斜的杆子测量和赌注点，线，道路或任何需要的东西。

新的Leica GS18 T - 与所有其他GNSS传感器不同

那么，倾斜补偿是如何工作的，如何消除对迭代设置流程的需求？对于GS18 T，Leica GeoSystems开发了一种非常特殊的IMU和一种专利的方法，可以将IMU和GNSS数据组合在一起。有了这项新技术，不再需要依靠磁力计计算每个测量的倾斜方向。具有倾斜补偿的GS18 T无校准，传感器不受磁干扰的影响。GS18 T不仅具有出色的使用能力，而且还用于衡量，因此GS18 T与目前市场上市场上的所有其他倾斜补偿传感器不同。

凝视变得容易得多，因为倾斜补偿消除了将气泡置于气泡以使杆垂直方向的需要。这意味着，在使用GS18 t出发时，工程师只需要执行以下两个步骤：

• Look at the setting out instructions and values on the controller screen
• 将极头尖端移至所需位置，使损耗值接近零

直观的利益：使用GS18 t杆的位置和极点到桩点的距离的距离在控制器上实时显示了具有强大的3D查看器的控制器。

以下视频序列给人以良好的印象：

As the setting out engineer does not need to ensure the pole is vertical by centering the pole bubble any more, the process is not iterative anymore. Setting out is much more comfortable and can be done faster than ever before.

与新的Leica GS18 tsetting out can be done quickly, confidently and accurately with the minimum of fuss and reduced stress. Simply get the job done on time.
