[FOSS-GPS] rtklib not outputting any solution

[sam at samthurtle.com.au]

Hello members of the FOSS-GPS mailing list.

My name is Sam. It is nice to e-meet you all, and I hope you can help me 
with an rtklib issue I am experiencing.

I have a U-blox NEO-M8P GPS receiver board connected via serial to my 
NVIDIA Jetson running Ubuntu 18.04.

I am trying to use rtklib-qt to apply RTK corrections via NTRIP and 
output a log file with the corrected solution. When I output the log 
file for the solution, it outputs an empty file.

If I output the raw GPS in NMEA, I can see the pre-corrected stream is 
output as expected.

If I output the correction stream in NMEA, I can see the corrections are 
being output as expected.

It is also worth mentioning that I was not able to get the solution 
results panel on the left of the main rtknavi window to display any 
data. It just shows "Solution: ----" and lat/long/height 0.

Has anybody experienced this before, and perhaps able to offer any 
advice?

I have also tested using rtklib 2.4.3 b34 on a Windows computer and I'm 
experiencing the same issue, so I expect it's more than likely a setup 
issue rather than a bug.

Please also see below some screenshots which may help in determining my 
issue. Thanks in advance.

Input window:
See attached 1_input_window.png.

Rover options:
See attached 2_input_window_rover_options.png.

Correction options (obfuscated for security, duh)
See attached 3_input_window_correction_options.png.

Output streams:
See attached 4_output_streams.png.
(I tried to output the solution as both Lat/Long/Height and NMEA0183).

Log outputs:
See attached 5_log_outputs.png.

Kind regards,
Sam
