Augmented stake-out

Leica GS18 T是第一个不受磁性干扰的倾斜补偿GNSS解决方案。现在，您无需垂直固定杆即可更快，更容易地测量任何点。特别是，您可以比以往任何时候都更有效，方便。

在这一专家见解中，我们将通过Leica GS18 T来研究重大变化和锻炼的重大变化。

The improvement of staking-out was possible due to the capability of the Leica GS18 T to derive precise heading information of the rover. Using the heading information, a graphics on a controller can be correctly oriented according to the actual heading of the GS18 T. In that way the elements of the real-world can be viewed within Leica Captivate从用户的角度来看，在利益点应用程序中。

使用GS18 t，不需要迭代点的迭代过程，因为杆不需要垂直固定。当以常规方式放入时，GNSS RTK ROVER需要朝向北部，太阳或其他典型方向定向。用户靠近桩点，垂直握住杆子并调节杆位。迭代重复此过程，直到坐标偏差在预定义的极限范围内。此外，可能会遇到用户目前不知道北方方向的位置。在多云的一天，人们甚至都看不到太阳。现在，可以通过在“利益点”应用中使用以下箭头来避免这些问题。用倾斜的杆子，可以将杆尖直接引导到固定点。因此，不再需要定位流动站并执行迭代的利益过程。

使用Leica GS18 T GNSS RTK ROVER的新方法

用以下箭头组合点

当用以下箭头静置时，GNSS RTK ROVER不需要针对任何预定义方向。以下箭头表明，必须根据当前运动方向移动到哪个方向。

Heading and direction of movement

运动的方向给出了t方向he user with the rover moves towards. It is determined from measured coordinate differences at consecutive epochs. As visualised in the figure below, the direction of movement is expressed with respect to the true North direction.

Using the following arrow makes staking-out much easier and more productive, as the live view on the controller enables users to orientate the GNSS RTK rover much faster. However, it is important to keep in mind that this method is reliable as long as the sensor moves around. Otherwise, the direction of movement cannot be accurately determined since the coordinates at consecutive epochs do not differ from each other anymore. The system can, therefore, not calculate towards which direction the GNSS RTK rover is oriented. Without this information the following arrow cannot navigate users towards the point to be staked-out anymore.

Staking-out with the Leica GS18 T

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.

As the direction of movement does not always coincide with the direction that the user faces, the heading of the GS18 T is used for navigating the following arrow in the Stake Point app. In this way, the user can more accurately see towards which direction the sensor has to be moved. Consequently, the performance of staking-out is increased and the time spent on the field is reduced.
