Real-Time Kinematics Explained

Real-Time Kinematics, or RTK, isn't the easiest concept to grasp. So we created this video to help explain how it works and how you can harness millimeter precision accuracy for your projects!

Minor correction... The L-band geosynchronous satellites aren't "somewhere over the southern hemisphere"... Yes, south of you, but it (and all other geosynchronous satellites) orbit over the equator.

Great video! Very informative on a subject I've always been curious about.

Great info. I'm researching the difficulty level of including an RTK system in a cinema drone, DIY version of DJI's Inspire. I want to use IR beacons or radio beacons...2 or more beacons. Not sure if DJI use radio or IR triangulation. It's a form of 'digital dolly' for their drone camera moves.

I've been an RTK user since the mid 90's. I have also set up and operated RTK networks. I am a trainer and on a standards development team for a large state DOT. There is some OK general information here, but I take issue with almost every assertion on this video. It is basically a sales pitch and should be taken as such.

This was actually super useful!
Do you ship to Kenya?

Actually, satellite clocks seem to tick SLOWER due to their relative motion. However, our clocks also tick slower due to our location inside earth's gravitational field. I believe that the gravity effect is about twice as large as the motion effect (though I might have these reversed, the factor of two is quite close). If I have which is largest correct, then the net compensation makes it seem that your misstatement is correct.

Enjoyed the video. I do have a question. For Bluetooth applications, can the rover unit be configured for ellipsoidal, geoidal with appropriate geoid model, or orthometric height? Antenna height? Thank you

What's the tiniest RTK module I can attach to a small drone? Also what is its max range?

[jomfawad]

Any plans on making emg sensors with dry electrodes?

[MrWaalkman]

@7:24 Here's my guess: Punkin Center?

What do you have for tracking objects within a building without using satellites?

[stagrei]

I have a stupid question. Is there a way to use a base station outside and transfer signal inside a building so I can get more precision when I scanning with SLAM technology ?

[tszabon]

Is there a technology that would enable RTK measurements in dense urban areas and in places surrounded by trees and tall buildings?
It would be a great help in my work (architectural visualizations) where we have to accurately and quickly measure points in "difficult" conditions.

[stephenmackay]

How much is the satellite subscription service for the L-Band after the 1 year service ends? Is there a way to get the 14mm accuracy without a subscription service?

[whatthefunction]

Why use the ground based stations if there is a satellite...? What am I missing

[fsn]

The prices for what it offers to surveyors are very illogical!
