You don't stricly need an expensive RTK to measure your GCPs. A simple Ublox M8P (or M8N) +special equipment ( for <500$ each in IP65 box ) +30min in static position+ Post-treatment, could give you less than 5cm of precision in XYZ. At this cost…"
this is an interesting test.
However I don't think that you prove that you have the right absolute position. You are "only" better in relative positionning.
I personnaly test the M8N/RTKLIB in RTK on geodesic points and I hardly find a fix…"
You can still use M8N for raw ouput and use it in RTKLIB 2.4.3 . However , you need to stay in FW2.01 (GPS+ Glonass) . The new FW3.01 (with galileo) doesn't work with RTKLIB.
M8T is much simpler to configure.
Be aware that the RTK option…"
I don't know if it could be your recent problem but have you checked around your radio receiver? If you have a Short Plug sytem for Channel setting , you may have had an external element on or in the pin.
I have had this rare problem in…"
I confirm that I use NEO-M8N-0.01 and RTKLIB is ok, as far as you stay in FW 2.01. ( doesn't work in 3.01 with Galileo addon. see https://github.com/tomojitakasu/RTKLIB/issues/134 ).
Obiously you are right and M8T is less tricky to configure. "
"Really impressive work Franklin.
Do you know RTKGPS+for android or the ublox C94-M8P with the buid in RTK and 3DR radio?
For the rover, I don’t think neither that the Orange pi is needed. You may request however a dedicate 3DR module and a…"
thanks for your nice 2 blogs about RX100 and Seagull parameter for image geotagg .
I am using MP1.3.39 and Arduplane 3.6.0 with seagull MAP2 and Sony RX100III, but I can't put RC6 (for you in your example, me it is RC8 ) in “RCpass Thu”…"
Good idea to build a simple CGP system. However I have the same feeling than Tom .
I guess that you build a raw datalogger and then YOU post-treat the signal with available Ntrip element (Why you mention certain country only ? ) around the…"
"Hi . I upgrade one M8N with this new firmware. However I noted a problem then on RTKlib that seem not recognise the GPS anymore .
Problem noted also with the android app RTKGPS+.
I came back to firmware 2.01."
Could be also interested to test your L1/L2 GPS equipment. I have already build cheap L1 only with Ublox M8N system for RTK and post treatment, but will consider the L1+ L2 difference.

If I understand your idea , you want to avoid Sd card and using 2 set of radios to send and stock raw signal directly on your computer.
I don't think that it will be so good because you will necessary have trouble via radio and you will…"
I confirm you that I a using the 2.4.3 Rtklib to save M8N raw information.
I don’t know about your solution with Arduino Uno and a Virtuabotix SD card reader/writer.
The solution I used is different. I was using initially a Ardulog data…"
"sorry sign "#"before mean "Comments". I only use the line for the TIM-FCHG .you can use all to insure:
!UBX CFG-GNSS 0 72 32 1 0 8 16 0 1 #Switch on GPS
!UBX CFG-GNSS 0 72 32 1 6 8 16 0 1 #Switch on Glonass
