GNSS reference station quality plots

GNSS satellite signal quality control is the process of evaluating the accuracy and reliability of satellite navigation system signals. Based on this, it will be known how well the positioning accuracy and positioning results are guaranteed.

The map displays the quality status of the GNSS signals recorded by the reference stations with a 1-2 minute delay. Green indicates that the quality of the GNSS signals recorded by the reference station is good. Yellow indicates weak and stronger signal interference. GNSS interference problems can be caused by intentional interference, unintentional interference or weather conditions. If the color is black, there is no connection to the real-time data stream of the GNSS reference station. This can be due to equipment malfunctions, server operation, power or internet outages, etc.

Selecting a GNSS reference station from the map or "Reference Stations" drop-down menu opens the reference station quality graphs. These graphs are interactive and the information on the graphs is in local time.
