When using the SAgro200 system for the first time, proper configuration is required to ensure that the system can communicate correctly with the vehicle, sensors, and correction source.

When working with GNSS receivers in real-world surveying, coordinate systems are often the first source of confusion—especially when switching between latitude/longitude and projected systems. To make GNSS coordinates practical for engineering calculations, we often use a map projection to convert the curved surface of the Earth into a flat, grid-based system.

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.

In modern GNSS surveying, stakeout tasks typically rely on maps with known coordinates. However, in some countries like the United States, Canada, or parts of Europe — especially when working with legacy survey maps, forestry records, or cadastral plans — point positions are are described not by coordinates, but by their azimuth and distance relationships.

When using an auto-steering system in the field, sometimes you may encounter areas without network coverage or RTK base. In such cases, you may still want to continue working without interruption. That's where PPP (Precise Point Positioning) comes in.

Global Navigation Satellite Systems (GNSS) are pivotal in providing accurate positioning and navigation services worldwide. Each GNSS system operates on a specific set of radio frequencies that enable the transmission of navigation signals. These frequencies are essential for ensuring that systems remain independent, prevent interference, and provide robust signals in various environments. In this article, we will explore the core concept of multi-frequency GNSS, examine the frequency bands of major GNSS systems, and discuss how multi-frequency technology enhances GNSS performance.
