Understanding DOP: The Hidden Factor Affecting GNSS Accuracy
Why does GNSS accuracy sometimes become unstable — even when signal strength looks good? One important reason is DOP (Dilution of Precision). In GNSS positioning, accuracy is not determined only...

How Satellite Orbit Errors Affect GNSS Accuracy
Why can a GNSS receiver still produce positioning errors even under open skies? Many people associate GNSS accuracy mainly with factors such as antenna quality, satellite visibility, multipath, or atmospheric...

Why GNSS Performance Changes in Different Environments
The same GNSS receiver can deliver very different performance depending on where it is used - sometimes varying by several times or even an order of magnitude. In open sky,...

Multipath Effects Explained: Why GNSS Positioning Fluctuates in Urban Areas
You may have noticed this before: your GNSS position works perfectly in open areas—but once you enter a city street, it starts to jump, drift, or fluctuate unexpectedly. Why does...

Why Does GNSS Position Drift When the Receiver Is Stationary?
Have you ever noticed a phenomenon like this: a GNSS receiver is clearly standing still, but its position keeps changing over time? In essence, this is the combined effect of several systematic...
