It may be not cheap if you're used to $25 boards; but it is DAMN cheap compared to other high precision GNSS solutions. The Septentrio mosaic-x5 is one amazing receiver.

Maybe Sparkfun should have a second KZfaq channel for hyper-expensive GNSS/RTK stuff. Kinda seems like a whole different business.

Hi Nathan. Can you demonstrate how this can be used with a PPK/RTK equipped drone? Most PPK/RTK drones use the RTCM3 protocol. Great product as always.

Nathan - take it a step further, you've got precise GNSS figured out and I can tell you it works well, even in Canada where things are cold and houses are expense LOL. Now, lets aim to create some precise drones that can take accurate positions using these base stations. Then lets add a nice lidar to it and voila, we are now mapping mother earth through the power of open source and man, I am game if you are haha.

Nice CERN T-shirt (I've got one, too). I work on CMS (the detector on the back of your shirt).

An included 4G module would be great.

Very interesting. Is the NMEA output 0183 or 2000 ?

Does it support Galileo HAS?

Ah, this will be quickly weaponized in Ukraine :) 🇺🇦
