DIY RTK GPS Drone Build | You'll never believe how accurate it is...

Conventional GPS on drones are good for basic navigation, but only get about 4-5 feet of accuracy. If you have an application that requires inch level precision, this just wouldn’t cut it. Thankfully, a proper RTK GPS set up can be used to get inch level precision. Until very recently, RTK GPS used to cost thousands of dollars. Today, you can get a module for $250 bucks.
But will it work on a drone? Getting the inch level accurate GPS coordinates are one thing, but can the autopilot use it for say… a novel approach to precision landing? Precision landing is a requirement for many drone delivery applications. The current standard for achieving precision landing (consistent lands under say.. a foot), are IR Lock and Computer Vision algorithms tracking an aruco marker.

If precision landing could be conducted with just an RTK GPS module, it would be a GAME CHANGER for drones. But can a pure RTK GPS solution to precision landing actually match the performance of other standards? That’s what we investigate in this video.

Love what you're doing!!! Keep up the good work; I've been doing this for years... Way to help out the community... In fact, I endorse your work and channel...

[@sanperez313]

Niceee demo!!! Can't wait to see what that here4 puck is like. It seems a lot better and sleek!

[@jashuaconstable4001]

Probably the most accurate drone build I’ve ever seen!

[@MaddManufacturing]

So my drone uses regular gps and can land on a dime because it also takes a picture during take off and re aligns during landing

[@frankdaze2353]

Good video bro. Keep it up!

[@lambo_drives]

Encouraging all around. amazed 🎉

[@ferrelldrewry]

Cool build. You're definitely well on your way to becoming ... another Bond villain ;-).

[@AsgardStudios]

Very interesting video. Thanks for sharing

[@alexconstable9401]

Best video ive ever watched keep up the great work

[@davidlee50]

So it is spot on in a gated community, cool. Clandestine missions here I come.

[@tf1389]

good job, and sense of humor :)

[@jpjpJPJPG]

pretty badass

[@bobzybob1]

Thank you, you guys are F*@# Awesome !!!!

[@TheLordSamoht]

It's the dancing squirrel for me!

[@navneetkumar7670]

Amazing 🤩, can you build it with a base station?

[@peek2much3]

WFT awesome video man!

[@anandkumar-wf1so]

Simply excellent...!!! hey dojo can you give more info on the RTK module ..i mean the product links etc..

[@thedronedojo]

Thank you!! Any board that uses the F9P ublox chip should work. I'm using the ardusimple board but the spark fun board would work as well

[@peter360adventures9]

Awesome

[@davidlee50]

You are the Jack Reacher of RTK!

[@BillyBonesYT]

Amazing video but bro... I call myself jank but this is another level 10:45 the extruder

[@goliathsuperstar]

that field is amazing, where is it

[@consig1iere294]

Quick question, doesn't RTK need a base station to function? Thanks.

[@tjjustvibing]

I'm trying to build a mapping Drone with rtk and a mechanical shutter. I am planning on trying to add a machine learning model on it in the future also. All the other parts are more basic. I need help finding the right parts and getting the Drone to work. Do you know of any people or resources that can help me?

[@ecsyntric]

you didn't talk about the rtk base/reference station. where was that placed?

[@helidrones]

I am wondering, if mobile base and fixed base station could be combined to eliminate the compass and have precision navigation at the same time.

[@vlad-st]

(polished by llama3 to ease the understanding, down you have the original idea that I was thinking from my ADHD mind)
The primary purpose of an RTK (Real-Time Kinematic) system is to calculate the deviation of the GPS location from a fixed reference point. This fixed point serves as a constant anchor, unaffected by changes in the GPS signal. When the GPS signal deviates from this fixed point, the RTK system sends the deviation data to the mobile station, which then uses this information to determine the true location, taking into account the deviation from the fixed reference point.
It's important to note that having two mobile stations, with one acting as an RTK, would not achieve the same result. This is because both mobile stations would still be relying on GPS signals, which can be affected by various sources of error. In this scenario, the 'RTK' mobile station would not provide a reliable fixed reference point, as it would still be subject to GPS signal deviations. As a result, the system would not be able to accurately calculate the deviations and provide a precise location.
Original from my ADHD brain: I think the need of an rtk is to calculate the deviation of the gps location from the fixed point (where it should be fixed always, regardless of the position signal from the GPS) - and when gps signal deviates from the fixed point (where it should be fixed): then it sends that gps deviation to the mobile station telling what is the true location including the deviation of the fixed point.

Now this is research that mads tech can't do

[@davidclaret1535]

How much cargo can a drone like this carry?

[@crazzyearl]

Are you using a local base station or an internet based service

[@thedronedojo]

For this video I was using an internet based base station. My phone hotspot was the 'in the field' router

[@jmc_fpv]

​@thedronedojo what this means. Can you give a quick explanation, please?

[@talknstang400]

Ur dog snd my dog must be related lol

[@superskeg]

Try simple syrup for bed adhesion

[@jewelkurianelias]

[@JoeKyser]

idk my landings are already ok

[@PhysicsKlub]

Your safe place. Lol

[@mouhsinesimo6540]

Contact please

[@Ngd9912]

I’ve been trying to contact customer service but had no luck can you pls check your emails

[@palindromic7873]

So where is the other component of the RTK system? It's all a bit vague. It's not a real RTK system. If it was then you could achieve 1cm.

[@chantryholdman3720]

Your drone is out of tune

[@izurzuhri]

Awesome

[@thedronedojo]

Thank you good sir!
