Today I finished the new version (third) of my GNSS.
For those interested I am sending photos and a 3D PDF.
In this PDF you can see all the elements I have installed so far via the Menu. It is very sensitive because in my Hobby laboratory (in the Basement with a small Window) it receives about 14 satellites.
I am very pleased because using standard elements I have obtained a very compact and nice Design. The GNSS has a built-in 868 MHz 100mW Transmitter and a 6000 mAh battery. I turn on the transmitter with a separate switch.
Let me know how you like this GSNN!

Hallo TS-Russell,
The accuracy is even in cloudy skies 10mm / diagonal 14mm. I use SAPOS NTRIP (Germany Bavaria 20 Euro/year) Service. Yes, I used 2 batteries for perfect balance in the mounting axis. ABS housing printed on BAMBU printer. I made the housing design in SOLIDWORKS.

This is such a cool project! Thank you for sharing Roman. I never expected a customer to re-use our mainboards. I thought it would be too difficult. You proved me wrong! Excellent work!
Hello Sparky,
it was no problem I bought 4 Ublox ZED-F9P desoldering boards from you to complete my project. When I got them my heart ached to desolder them. Then I decided to check them, all of them had damage, in the first one the choke for powering the antenna was missing, in the second one the mcp73833 was damaged, in the third one the max17048 was damaged, in the fourth one I had to reinsert J8 and J18.
I repaired all of them and they work great.
Now I’m wondering what to do next, something interesting!.
It would be interesting to replace the batteries (which are heavy) with round 21700 and put them in the pipe at the very bottom. Then the antenna with electronics at the top would be very light and it would improve the comfort of work.
I just need to think of how to divide the carbon tube and add contacts so that the current from the bottom goes through 2 to 3 segments. but that will probably be a trifle.
I still have many ideas, I also ordered IM23-TCA and IM19 and I will try to make some compensation for the antenna angle.
