What is Real-Time Kinematic (RTK) and how does it work?

Real-Time Kinematic (RTK) is a technique used to enhance the precision of position data derived from satellite-based positioning systems (global navigation satellite systems, GNSS) such as GPS, GLONASS, Galileo, NavIC and BeiDou. It uses measurements of the phase of the signal's carrier wave in addition to the information content of the signal and relies on a single reference station or interpolated virtual station to provide real-time corrections, providing up to centimeter-level accuracy.

Short and precise. Perfect!

[@RogerGarrett]

That video is NOT a good description of how it works. The TEXT description touches on the actual method it uses: "It uses measurements of the phase of the signal's carrier wave" but fails to explain HOW it detects the phase of the wave, HOW such detection is used to calculate "correction data" to be sent to the rover, what that correction data looks like, and HOW it is used at the rover to produce centimeter-level accuracy of its position.

@@TheRealCheckmate I wish I could. It's what I was looking to learn when I came across this video. I'm sure it's a video somewhere, just not this one. And I've since moved on to different projects not requiring RTK.

@@RogerGarrett I'm trying to get just the gist of how RTK really works, but every video is too generic. I'm glad I'm not alone.

[@elvinmartin1027]

This video is just about DGPS(differential gps) . RTK includes measuring the phase and no. Of wave cycles B/w the satellite and the reciever.

Wonderful video. Thank you !

[@ed9694]

how long will it take to measure the elevation of a specific points and whats it maximum range of rover from the base station

[@EricPham-gr8pg]

The power of GPS is that if advance instrument can drive background sound to do almost anything even moving object. Rearrange furnisture or clean up the house , garden work ect or clean up after children with a click of a button

Code based system is DGNSS

Should had two ways protecting dignitary in mitigate safe operation of all system in proximity

If the concept is this simple, why does it cost so much?

They do not provide “centimeter level accuracy.”

[@super9mega]

I was under the understanding that certain ones can even provide millimeter level accuracy, can you explain what you mean by that? I've never heard anything other than the marketing terms

[@Dizzilnate]

Yes they do. I'm American, so ours measures down to three hundredths of a foot.
