What Does GNSS Stand For? Modern navigation technology has become part of everyday life and is widely used in a variety of industries to improve efficiency and accuracy. When it comes to navigation, however, the average layman only knows the term GPS. As a surveyor, you understand that the...
GPS vs. GNSS: What is the difference? GNSS is a way of describing every satellite constellation in orbit; GPS is one of several constellations making up GNSS. From GPS to GLONASS (operated by Roscosmos State Corporation for Space Activities in Russia), many constellations make up GNSS. Positi...
A GPS is considered to be a Global Navigation Satellite System (GNSS) — meaning it is a satellite navigation system with global coverage. As of 2020, there are two fully operational global navigation satellite systems: the U.S. navigation signal timing and ranging (NAVSTAR) GPS and Russia’...
The GNSS is a satellite navigation system that provides global coverage of geospatial positioning. The satellite navigation systems of different countries operate under GNSS. GPS has now become so popular that people mistake every satellite system with GPS, but that is far from the case, as the l...
Since 2023, Galileo has had thehighest accuracyof all three GNSS with a horizontal accuracy of 20cm and a vertical accuracy of 40cm. That is impressive if you compare Galileo to GPS or GLONASS. However, just be aware that your device needs to be able to communicate with the Galileo system...
We can see that the position error in forward processing grows exponentially until the GNSS is back after 60 seconds. The same can be seen in the backward data where we lose the GNSS at 60 seconds, and the error grows exponentially until the GNSS is back at the 0-second mark. When we...

GPS/GNSS Spoofing vs Jamming Both jamming and spoofing are a type of GNSS radio interference that happens when weak GNSS signals are overpowered by stronger radio signals on the same frequency. Jamming is a kind of ‘white noise’ interference, causing loss of accuracy and potentially loss of ...
GNSS multipath mitigation, also often called GPS multipath mitigation, is the process of minimizing or correcting multipath errors.Link to download the multipath mitigation poster. What is multipath error? Multipath error is also often referred to as GPS multipath, GPS error, GNSS multipath, multipath...
