When conducting surveys, even small errors in base station coordinates can affect the accuracy of your measurements. To address this, most surveying software provides a function called Calibrate Point/Grid Shift. But do you know when you should use it and why it's necessary? This blog will guide you through it.

In GNSS surveying, understanding satellite availability and distribution is essential for accurate measurements. One of the most intuitive tools for this purpose is the Skyplot—a visual representation of the satellites above your survey point.

In most routine RTK stakeout tasks, surveyors depend on the compass of their data collector (or smartphone) to guide the stakeout direction. This usually works well, but in certain environments—such as construction sites with strong electromagnetic interference—the compass may become inaccurate or even completely unusable.

In our previous post, we explained the basics of GNSS antenna calibration and the role of NGS certification. This time, we'll take a closer look at the calibration files produced by NGS—ANTEX and ANTINFO—and how these files can be understood and applied in real GNSS workflows.

The data collector is one of the most widely used tools in modern GNSS surveying. They allow users to configure base and rover stations, collect measurements, and manage survey data.

In daily measurement work, we may often need to change the coordinates - like local coordinates conversion or base reference shift. Our SingularPad field surveying software provides three methods to achieve this: Localization, Calibrate Point, and Post-Measure Correction.
