The Leica GS18 T is the first tilt compensating GNSS solution that is immune to magnetic disturbances. Now you can measure any point faster and easier without the need to hold the pole vertically. In particular, you can stake-out more efficiently and conveniently than ever before.

In this Expert Insights we will take a look at major changes and improvements of staking-out with the Leica GS18 T.

由于Leica GS18 t能够得出流动站的精确标题信息，因此可以改善静止状态。使用标题信息，可以根据GS18 T的实际标题正确定向控制器上的图形。以这种方式，可以在内部查看现实世界的元素 Leica Captivatein Stake Points app from the user’s point of view.

With the GS18 T the iterative process of staking points is not required, as the pole does not need to be hold vertically anymore. When staking-out in a conventional manner, a GNSS RTK rover needs to be oriented either towards the North, the Sun, or to some other typical direction. The user goes close to the stake point, holds the pole vertically and adjusts the pole position. This process is iteratively repeated until the coordinate deviations are within the predefined limits. In addition, it may happen that the user does not know where the North direction is at the moment. On a cloudy day one may not even be able to see the Sun. These problems can now be avoided by using the following arrow in the Stake Points app. With a tilt-compensated pole, the pole tip can be directly guided to the staked point. Therefore, there is no need anymore to orientate the rover and to perform the iterative stake-out process.

New way of staking points with the Leica GS18 T GNSS RTK rover

Staking points with the following arrow

When staking-out with the following arrow, a GNSS RTK rover does not need to be oriented towards any predefined direction. The following arrow shows in which direction the rover has to be moved according to the current direction of movement.

Heading and direction of movement

运动方向呈现了用户随漫游者向朝向的方向。它是根据连续时期的测量坐标差异确定的。如下图所示，运动方向相对于真实的北方方向表示。

使用以下箭头可以使静止状态变得更加容易，更有生产力，因为控制器上的实时视图使用户可以更快地将GNSS RTK ROVER定向。但是，重要的是要记住，只要传感器移动，该方法是可靠的。否则，无法准确确定运动方向，因为连续时期的坐标不再彼此差异。因此，系统不能计算出GNSS RTK ROVER定向的方向。没有这些信息，以下箭头将无法将用户导航到要插入的点。

Due to the inertial measurement unit (IMU) integrated in the GS18 T, the rover has the ability to determine its heading. As visualised in the figure below, the heading describes the direction the controller points towards. This is also the direction the user faces. In order to correctly determine the heading, the GS18 T has to be correctly aligned with the controller. This means, the user interface on the GS18 T has to face the user. The heading is expressed with the respect to the true North direction.

由于运动的方向并不总是与用户面对的方向一致，因此GS18 T的标题用于在Stake Point应用程序中导航以下箭头。这样，用户可以更准确地查看必须朝哪个方向移动的方向。因此，排便的性能增加了，并减少了在场上花费的时间。

Leica Captivate and augmented stake-out

The real-world elements of the area to be staked-out can be visualised within the Leica Captivate software. As shown in the image below, these elements can be either a scan of a building or a drawing in dxf file of the objects located in this area.
