Determine your location to the centimeter around the globe? For everybody, not only for the military? Only with an ESP32 and a decent GPS receiver module? Not possible! Wrong; it is possible by using real-time kinematics. You can even earn money by building a base station and connecting it to a global network (Decentralized physical infrastructure network)!.
When I got a board from Michael, a viewer of this channel, I was hooked on trying to understand this relatively new technology. Are you interested, too? Then, follow along.

Please order the "S" type of the antenna (all band). It is in the same link I provided.

There were people who figured this out ... and then there are people who think the world is flat.

Knowing how GPS works only makes it seem more impossible. The precision is hard to comprehend.

@mapgeek6 2 years ago

Part of the reason that the US Military stopped degrading signals after the Gulf War is because scientists and land surveyors had already figured out how to get drastically improved results even with the degraded signals. But RTK is even better with non-degraded signals we all have access to today. I love this video!

Fun fact: the GNSS satellites constantly apply corrections to their timers, because they move fast enough and need to measure time precise enough that relativistic time dilation becomes relevant. 🙂

I too pay my respect to the engineers 40 years ago who devised this technology. Amazing

I'm an engineer in Brazil, power electronics and lately developing circuits for use in the field in agriculture. The use of RTK was discussed the year before last, but it was not applied Brazil everything is very expensive and bureaucratic. It was used for planting with tractors. Today this idea was abandoned and they hired the company Kimble .. today my project consists of lora modules with the llc68.. where each device has 4 inputs, 4 isolated outputs, 1 GPS, and a Gateway with just 1 GPS module and covers 5km.. tractors, gates, motor pumps, sirens, everything done by this system...your videos are the best...congratulations

The first GPS receiver I used was a Sony Pyxis in 1992. It chewed through a pile of AA batteries in just a few hours and it took something like 10 minutes to lock on every time, and it couldn't deal with even a little bit of tree cover or heavier clouds. I now have a < $100 watch that can get a lock INSIDE a lot of the time in just a few seconds and can track for many hours on a tiny internal battery.

Absolutelly great video. I looked at RTK 10years ago and it was just out of reach.. Now it seems nearly magically simple.. Amazing times.

if we could select a handful of people to make immortal so they can keep innovating and moving our civilization forward, i'd nominate this guy.

Crazy! I’ve been into AG RTK for over 15 years for sure and probably have close to 500k into gear.
Warms my heart to see you put together a base station for $300! I want to say my first station way back then was $50k!

Andreas, would you please stop filling my aliexpress shopping cart?

For less that $15, we built a GPS tracker for the kids model rockets using a Arduino, a barometric presser sensor, a long range communication module and a GPS module. Even had a custom printed circuit board made for it. It transmits latt, long and altitude back to a base station. We can then punch those coordinates into a mapping app and it takes us directly to our downed rocket.

In the 1970s I was an engineer in the USAF working in the building next to the GPS development building. Every year we got to see briefing charts showing the GPS receivers on the back of a deuce and a half truck with the concept drawing showing that, one day, perhaps every Army platoon might have a guy with a GPS backpack, so they could take advantage of the technology and not just ships and airplanes.

I've got one of those gps guided mowers, Luba 2. It is mind blowing how precise it is. It runs right up to my curb consistently. RTK is a gamechanger.

@amorpheuses1627 2 years ago

As your subscribers we too want more. I would second the suggestion already made by a viewer: another video on base station setup. I was hoping this video would cover that but that would have made it too long. I know you weren't planning on doing one but I and I'm sure others would very greatly appreciate it. At any rate, thanks very much for the video - very interesting technology. All the Best!

Dude with the Swiss accent, you are awesome! Thanks so much for sharing this information with us! I love your content! ❤️

I was a deputy test director for the first USA military gps application in the world back in 1989 : Rockwell Collins and TI manpack/vehicle test and Marine test. They were accurate to hit a 1/2 dollar size coin benchmark.

Your explanatory videos are stupendously useful Andreas. Thank you!

Original Garmin 1993 was funny. It did not work right in the southern hemisphere. I bicycled in Australia and it reported negative speeds and sun rising in the evening.
