GNSS出现，无需垂直平整杆位吗？

Setting out with a GNSS antenna is a tricky task. Looking at the instructions and values on the controller screen, moving the pole to the required position, and ensuring the pole is vertical by centering the pole bubble - all at the same time - needs careful execution and is not easy, especially when time pressure is high. With the newLeica GS18 T，设置比以往任何时候都更加方便，更快。保罗·戴尼（Paul Dainty）在本文中解释了更多。

测量师和设定工程师没有什么不同。工作压力很高。在典型的建筑工地上，通常要执行一些关键的时间任务，例如检查欠建的结构或设置土方工程或建筑基金会。

The pressure is on. A crew and an expensive machine are waiting。

可是有时,网站可以意图的压力lly high. Imagine, the excavator machine has just arrived on site earlier than planned and it is ready to start the earthworks. The problem is the profile boards have not been set out, and this needs to be done before the earthworks can start. The setting out engineer is the only person who can do this. The pressure is on. He must set out these profile boards right now, as fast as possible, to the highest possible accuracy of course while a very expensive machine is waiting idle, not to even mention dozens of impatient workers.

Setting out with a conventional GNSS RTK rover can be slow

使用常规的GNSS RTK漫游者，设置是一个相当缓慢而有条不紊的过程。这是因为需要在将杆将杆移入到位的同时，同时在控制器屏幕上查看设置信息的同时垂直固定。GNSS位置计算为固定在1.8 m或2 m极上的天线。因此，为了使屏幕上的列出信息正确，必须通过将杆气泡垂直固定杆。

要准确地设置职位，需要同时执行多个任务：

• 查看控制器屏幕上的设置说明和值
• 步行和定向：将杆移至所需位置，使损耗值接近零
• 通过居中杆气泡来确保杆垂直

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。

由于同时执行所有这些工作非常困难，因此通常优先选择在迭代过程中遵循这些任务：

它需要是一个迭代过程，因为通过将气泡居中以确保杆在步骤3中垂直，我们可能需要移动天线，并且需要再次进入步骤1以检查屏幕上的设置说明。然后再次执行步骤2以调整杆位，依此类推。要准确地设置一个位置，可能必须执行两次或三次的过程，这并不是特别困难，但是确实需要时间才能正确地进行操作。

现在返回我们的网站，想象一下挖掘机和工人的工作人员等待您仔细列出个人资料板，并在每个过程上执行迭代设置过程。这种情况可能会非常压力，并且可能会发生错误，从而进一步降低了过程。

Imagine being able to set out without needing to perform this iterative process.

Well, now that is possible, using theLeica GS18 T带有倾斜补偿。GS18 T是第一批允许用倾斜的杆子堆放的GNSS RTK ROVER。因为GS18 t与Leica Captivatefield software, tilt compensated measurements are possible in any app within the software. We can measure and stake points, lines, roads or whatever is needed, all with a tilted pole.

The new Leica GS18 T – different from all other GNSS sensors

So how does the tilt compensation work and how does it remove the need for the iterative setting out process? For the GS18 T, Leica Geosystems developed a very special IMU and a patented method of combining the IMU and GNSS data. With this new technology, it is not necessary anymore to rely on a magnetometer to calculate the tilt direction for each measurement. The GS18 T with tilt compensation is calibration free and the sensor is immune to magnetic disturbances. With its remarkable ability to use it not only for measuring but also for staking out, the GS18 T is different from all other tilt compensating GNSS sensors currently in the market.

Setting out is made much easier because the tilt compensation removes the need to center the bubble to make the pole vertical. This means that when setting out with the GS18 T, the engineer only needs to do the following two steps:

• 查看控制器屏幕上的设置说明和值
• Move the pole tip to the required position so that the stake values are close to zero

Intuitive stake out: With the GS18 T the position of the pole and the distance of the pole tip to the stake point are graphically shown in real time on the controller with a powerful 3D viewer.

The following video sequence gives a good impression how it works:

由于设置工程师不需要通过将杆子气泡居中来确保杆垂直，因此该过程不再迭代了。凝视要舒适得多，并且可以比以往任何时候都更快。

通过新的Leica GS18 T设置可以快速，自信，准确地完成最小的大惊小怪和减轻的压力。只需按时完成工作即可。
