What Causes Weak GNSS Signals and How to Read SNR
Have you ever encountered this while using a GNSS receiver: the device suddenly reports “weak signal,” the position updates lag, or even in a seemingly open area like a parking...

Speeding Up GNSS Positioning: Cold, Warm, and Hot Start Explained
When using a GNSS receiver, the time it takes to obtain the first position fix—commonly called Time to First Fix (TTFF)—can vary widely. Sometimes your receiver locks onto a position...

Does Weather Affect GNSS Positioning Accuracy?
When GNSS positioning performance degrades, one of the first questions asked is always: “Is it because of the weather?” Rain, clouds, fog, or snow are frequently blamed for unstable positioning. But...

How Geomagnetic Storms and Ionospheric Activity Affect GNSS Performance
GNSS positioning accuracy depends not only on receiver performance and algorithms, but also on space weather conditions. During periods of strong solar activity—especially geomagnetic storms—GNSS users may experience reduced accuracy,...
