Why Does GNSS Require at Least 4 Satellites for Positioning?
Have you ever wondered this: when using satellite navigation, we notice that the receiver can pick up signals from dozens of satellites. Yet, geometrically, only three satellites should be enough...

Do I Really Need Centimeter-Level GNSS Accuracy?
When exploring GNSS solutions, “centimeter-level accuracy” is often presented as the gold standard. Precision agriculture, surveying, and automation all seem to point in one direction: higher accuracy is better. But a...

GNSS vs GPS vs BeiDou: What’s the Difference?
Do you often hear terms like “GPS navigation,” “the BeiDou system,” or “GNSS,” but still find it hard to tell the difference between them? Today, we’ll explain these concepts in...

Beyond GPS: What Other Global Navigation Satellite Systems Exist?
When people think of satellite navigation, GPS is often the first—and sometimes the only—system that comes to mind. In reality, GPS is just one part of a much larger global...

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,...
