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.

Before RTK days, I worked at a drone company in 2014 and we spent months trying to get an accurate landing with lasers, etc. RTK was a game changer it came out

[TheLordSamoht]

It's the dancing squirrel for me!

[PharnsGenece]

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...

[davidlee]

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

[jashuaconstable]

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

[ecsyntric]

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

[anandkumar-wfso]

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

[sanperez]

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

[consigiere]

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

[PlanB-]

Awesome work👍
But do you have to have a base_mount in order to use RTK?
Cheers.

[alizuma]

I don’t know if this is true rtk as you need a base station that the drone uses as a reference point. Did you have that or are you using some kind of service like Ntrip or Rtk2go?

[navneetkumar]

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

[ferrelldrewry]

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

[crazzyearl]

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

[BillyBonesYT]

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

[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

OG dji chassis, classic
Wires everywhere, classic
Pixhawk, classic
Double sided tape, classic

Listening to those motors oscillate, unacceptable 😅

[LehtusBphreeflyFPV]

Now this is research that mads tech can't do

[AsgardStudios]

Very interesting video. Thanks for sharing

[VIPERMARINE]

Love your vids we definitely need to collaborate again.
