How RTK works

In this video, we will talk about the technique called real-time kinematic, or RTK. RTK is used to enhance the positioning accuracy of the GNSS. With an RTK-capable receiver, you can measure your position with centimeter accuracy. Therefore such receivers are irreplaceable when it comes to land surveying and other applications where you need to know your exact position.

Hi, what is the accuracy difference using only one Emlid SR2+ as a rover with RTK via NTRIP (with wifi cellphone) vs one SR2+ as a rover and another one as a base like in the video ?

Pretty good simplification of the current state of RTK. I've been using RTK for almost 30 years, have built and operated an RTK network, train people on how to use it and help develop standards for its use with a major state DOT.

Your distance error statement was not correct in my opinion, at least for this level of discussion. In my opinion, you should simply have described the distant dependent error. Saying it is good or not at a range depends on the precision/accuracy needed, and that varies. RTK is entirely appropriate at 50im, for certain applications (single or multi-band) Single band RTK isn't just limited to 10km, It has more to do with the integer ambiguity (described) and often having to fix over a known point. Multiband RTK has near instantaneous 'fix' and can better correct for ionospheric error, which does impact the distance dependent error, but not by much for RTK.

This is a good quick description overall, and one that I would use if I were to put it in context.

Thank you so much, this helped a lot!

S22 supports carrier phase if I am not mistaking. RTCM messages can be received from any free nearby station.

Is there nothing preventing my phone from achieving <10cm accuracy then?

With RTK do you need a rover? Or would a Drone with an RTK module count as the rover in this case?

[cjleongson]

Can you like have an rtk drone to aid the rover and base when its hard to find signal because of say vegetation?

[alhdlakhfdqw]

really incredible videos thank you very much! subbed :)

[blain]

How is the known control point determined?

[bhupendrakumar]

is it necessary that satellite is same for rover and receiver?

[droneoccitanie]

Great.
Is it possible to achieve millimetric precision ?

Doesn't say much.. gloss over many details!

I learned the RTK survey Can anybody help me in pakistan ??

But we need explanation about

Please note NOT PPK.... We need static

[doormanfoc]

All the license "professional" surveyors that I hired and personally witnessed stake out a worksite using just the carry around one... I would always double checking their work measuring physicals tools it has always been off by a whole six inches to a foot no matter who I hired. Now watching this video and knowing that none of them use proper equipment to give us accurate information I am fuming at how much money was wasted paying those lazy cheap frauds. Should/can I sue them?

[stargazer]

How RTK works: math and handwaving. This explained nothing. How about explaining those complicated calculations at least a little bit?

[aprillakilak]

This is the only explanation I found that actually made sense to my non-surveyor soul 🥲thank you so so much
