How does GPS work?
In this video, we deep dive into the math behind the Global Positioning System (GPS). Using simple ideas of geometry, we can accurately determine any location on Earth.
Mathematical thinking skills help us solve problems, and understand and see the world more clearly.

This is very well illustrated and explained, thanks! I've gone through many videos explaining GPS, this is the best! 🤗
This channel's videos should get millions of views!! ❤
Excellent Sir. Good Work.
Your channel is a blessing
Very good explanation. Thank you
Excellent
I have a quick question: Wouldn't 3 GPS satellites suffice to pinpoint your exact location on earth? Since you will always get two intersection points, one located on the face of the earth and one somewhere in outer space, couldn't we assume that we are located on the earth?

the GPS receiver cannot see the earth so it cannot know which of the two points is on the surface

Explanation in the video is wrong. The 4th sattelite is needed, because the other three distances cant be calculated without error. Thisxerror comes from the unknown sattelite time vs own unprecise timecreference
Thank you for making such good content.
Will explain 😊😊❤
Manan sir aapke bolne ka tareeka kamal hai…. Mujhe aapko hindi mein sunna hai… aapki audience badh jayegi…. Majaaa aa gaya sun kar and aapko dekh kar… wonderfully explained
Thank you Manan sir 😊
Sir, Is this that simple to Understand!!! And You made it! Hearing you teach, motivates to teach anything as simple as possible to students! Thank You for sharing your knowledge into simple pieces.
thnks
I suspect that not every GPS receiver has an atomic clock. How will it work then ? only from the time difference between the received times ?

If the clock in your receiver is off (and it almost certainly will be as most receivers don't contain an atomic clock), the spheres won't intersect at a point. Going back to the 2D example because it's easier to visualise, the circles won't meet at a point but will form a "triangle" with three curved sides. The receiver can use this triangle to work out how much it needs to alter its clock so that the circles will meet at a point, then rerun the calculation with this new clock value.

No GPS receiver has atomic clock, It's GPS satellites that have atomic clock synced, GPS receiver simply receives signals from all these satellites and calculates differences in the received time from each satellite.
KZread channel name Mujtaba like a good time
That "turd flag" really made the difference!
