I have the NEO-M8P gps board connected to a GPS-15192 antenna and it seems to be working, putting out a .ubx file that looks correct as shown in the attachment. When I load it into RTKLIB rtkconv no obs file is created. When convert is pushed it flashes the abort as though it is going to run then immediatly returns to convert, so no conversion is done and no obs file occurs in the directory. Attached also is the setup for the rtkconv. I have tried setting time limits with the same lack of results. The only forum post similar to this solved by eliminating corrupt data but the data seems OK and I have tried many ubx files. Can anyone suggest other reasons for this inability to convert? Thanks.
I believe you need the RXM-RAWX and RXM-SFRBX messsges in the .ubx file. I don’t see those in your screen shot. It looks like you have mostly solution and ephemeris messages in your file. I’m not a user of that exact chip so take this, especially the exact message types, with a grain of salt.
As the usual purpose of the raw files is to post process the raw observables to determine better solutions than were determined in real time, you need the raw observables.
You look to have enabled a lot of unnecessary messages, probably an old .CMD script for RTKLIB. Stop blindly running the wrong scripts, and pick device appropriate ones.
Among them TRK-SFRB and TRK-MEAS, these aren’t going to work for you in this context.
You need UBX-RXM-RAW(X) to get Observations out of recent uBlox receivers.
You can usually source Navigation files from your CORS, NOAA CORS carries all-stations Navigation (Ephemeris) and also .SP3 Precise Ephemeris.
Thanks for the comments. I naively tried to follow the reference station tutorial, including enabling the RXM-RAWX messages, but I may not have saved correctly. I will go to the chip instructions and try to learn how to correctly get the right messages and get rid of the others.
