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

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

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

  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

  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.

  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

  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.

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

  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.

  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.
