The Difference Between GPS & GNSS

Watch our new video to learn how GPS & GNSS works and the difference between the two.

In simple terms, GNSS is the term for the overarching umbrella of global navigational satellite systems under its network:
GPS = USA
GLONASS = Russia
BeiDou = China/Asia
Galileo = Europe

One of the vital pieces to the Inertial Sense navigation system is GPS, or as we know it across the world, as GNSS.

GPS stands for global positioning system. GNSS stands for global navigation satellite system.
The difference between GPS or GNSS is basic. It is a position that we receive on the earth that comes from a satellite. We send a message up to the satellite, and it comes back down to tell us our location. These satellites revolve around the earth. This satellite particularly, specific to the US or to the Americas, is called GPS.

GNSS is more broad because the satellite covers a wider scope. Europe has its own constellations of satellites that are revolving. Australia has its own constellations and satellites that are revolving around the earth. China also has satellites that are revolving around the earth.
The entire network, composed of GPS constellations, including Beidou, Galileo, Glonass, all make up what we call GNSS.

No matter which market you are in, our sensor is going to ping those satellites and be able to tell you exactly where you are. It is a global network of satellites that are working in harmony to give you a position.

If you have any questions about which constellations we support, which ones will work with our sensors, give us a call or visit our website to chat, and we will be more than happy to help you find what is best for you.

"We send basically a message up to the satellite and the satellite comes back down and tells us where we are."

*No!* That absolutely doesn't happen. Those satellites don't receive anything at all, and they don't know where your device is.

[donbeckham]

Your sensor does not ping the satellites.

[IgorFuna]

We send a message to the satellite? Do you actually know how GPS works?

Thank you so much now this makes sense to me and I'm able to understand it, you're really a good teacher!!!
Anyways, I want hear also more about Site-specific management as well as precision agriculture and these approaches are linked with GPS and GNSS.
Thanks!.

[인조히]

Thank you. I understand it very clearly!

[GlennThompson]

This fellow is far too clever for me, this is way above my head. Such busy little satellites telling every phone and car where they are. When do they sleep??

Thank you pretty much for this informative video about the difference between GPS and GNSS. Could you possibly illustrate how an aircraft executes a GNSS procedure? Many thanks in advance.

[hardytall]

Are mobile phones connected to gnss or gps ?

[dprintedrc]

So a GN main talker is more stable then a GP main talker, but can be alittle slower in update rate due to multi protocol, is this correct?

[paulchacko]

Only one small mistake : GPS receiver does not send or transmit any thing to satellite

....Connor McGregor?!
U look like him lol 😆 but seriously you explained this so well.

[NonArkara-hlmc]

So. Is GNSS a better system? Because more satellites working together is better than just one country’s?

[F-rig]

How well does Beidou (BDM) work in the americas?

[seangustavson]

Flagrantly wrong and misleading video. Your device absolutely does not communicate with satellites, GPS L1, 2 are STRICTLY one-directional. Do better.
