Error running NRcan rinex observation
When running a NRCAN rinex file out of X5 receiving ERROR mail. Error : A duplicate data block has been found in your RINEX observation file at epoch 2025 02 11 00 41 30.00. Please correct and resubmit.
Software/Hardware (please complete the following information):
- RTKBase release number 2.6.2
- SBC Orange pi zero 3
- GNSS Device: simpleRTK3B Pro antenna beitian bt-800S
- Connection type: USB
I can repro this problem. It's related to something wrong in rtklib b34j. If you want, you can test this workaround :
cd ~
rm install.sh
wget https://raw.githubusercontent.com/Stefal/rtkbase/refs/heads/rtklib_b34k/tools/install.sh -O install.sh
chmod +x install.sh
sudo ./install.sh --rtklib
It will stop the various services, and upgrade rtklib to release b34k. Then, create the rinex file again.
Please keep me informed.
RTKBASE shows: Failed! There is more than 1 file in the archive you want to convert. The reason could be a power outage or a main service stop/start. Please try with an archive containing only one file
I reopen this ticket to not forget that I should update RTKLib for the next release.
Thank you for your excellent work Stafal!
Probably a related problem. I got a similar error back from NRcan:
Error : A duplicate data block has been found in your RINEX observation file at epoch 2025 08 31 00 09 00.00. Please correct and resubmit.
I tried multiple days and settings:
Error : A duplicate data block has been found in your RINEX observation file at epoch 2025 09 01 00 06 30.00. Please correct and resubmit.
I couldn't try the workaround because the rtklib installation file does not exsist anymore.
I succeeded to get a report when using the ign specific rinex export. But this one is only based on GPS-signals and I get the warning:
Warning : No (NULL) APC to ARP was applied. This may be due to a missing or invalid antenna record in your RINEX file or the absence of phase centre information in the IGS/NGS ANTEX file for your antenna. Ensure that both the antenna type and the RINEX header record "ANT # / TYPE " are valid. Estimated height should be used with caution.
My hardware: RTKBase release number 2.6.3 Raspberry Pi 5 Model B Rev 1.1 Septentrio_Mosaic-X5 - 4.14.4 Connection type: USB
As a side note: the NRcan specific export consists out of GPS + GLONASS signals while NRcan supports also signals from the Galileo constellation.
@GertS You can download the sbf file, and convert it with another computer and a more recent release of RTKLib. The next RTKBase release will use RTKLib v2.5 EX.
The fix for using Galileo is already merged in the dev branch.
