Some events are doubled

Emlid Studio Drone data processing
1

Hi,
Thank you for this new version.
I detected a small bug in the last version of sutdio.
Some events are listed 2 times consecutively in the _event file with exactly the same time values (and other parameters are also the same). 2 times for around 400 events.
I compared with RTKLIB processing and the problem does not exist.
So I analyse the RINEX file and found that there is a flag in the line before the doublon events:

" Time mark is not valid COMMENT
" > 2021 7 9 12 19 31.7096683 5 0

I hope it could help you.

I am sorry but as a new user I cannot upload files :face_with_raised_eyebrow:

Hi @laurn,

Can you share the firmware version of your Reach and the logs (the RINEX ones and _events.pos from Emlid Studio and RTKLib)? It will help me see why it happens.

Hi @laurn,

I’d suggest using a file exchanger such as WeTransfer or Google Drive.

@laurn,

Thanks! Can you send the RINEX navigation data too? It’s needed to process the logs.

Hi @laurn,

Great, thank you! I’ll look into the logs and will be here with the news.

Hi Ksenila,

As I wrote to you in my first post, I analyse the RINEX file and found that there is a flag in the line before the doublon events:
" Time mark is not valid COMMENT
" > 2021 7 9 12 19 31.7096683 5 0
Direct PPK computation with RTKLIB is correct, the bug is only with Studio.

Hi @laurn,

I see. Which firmware version is installed on your receivers? Do you have UBX logs from this flight?
