I have my RTK mosaic-X5 set up and working as a CORS. It sends NTRIP to RTK2GO and I have it creating and uploading RINEX files that I am able to access via an FTP site. My problem is that the RINEX files don’t have antenna info. I tried using the Septentrino Web interface, but can’t seem to find any avenue to set this info. Could someone please walk me through this?
Thanks!
There should be a setting for “ARP” or similar that will allow you to input the antenna’s specs (ARP = antenna reference point)
Here are some links for detailed info on the antenna:
This antenna has been certified by the National Geodetic Survey. The ANTEX and ANTINFO are available. You can see the full listing under SFESPK6618H on the NGS Antenna Calibrations website.
Hi @Agcopter ,
I think you might be looking for setAntennaOffset? But this is an RTCM setting, not RINEX specifically…
“
2. For RTCM 3.x, the antenna information in message types 1007, 1008 and 1033 can be specified using the setAntennaOffset command, with the serial number as sixth argument, and the antenna type (called “antenna descriptor” in RTCM) as fifth argument (see also section 2.5). For instance: setAntennaOffset,Main,“AT2775-54SW”,“5684”
“
Please have a look through the firmware reference guide:
I hope this helps,
Paul

My Rinex files still get rejected. Can anyone tell me how to enter the antenna info so that the RINEX files correctly give all the antenna info.
Hi @Agcopter ,
I suspect the antenna info may be a red herring, but I’m not sure.
Which service are you submitting the Rinex file to? CSRS (NRCAN), OPUS, or somewhere else?
Have you got any more details about why the file is being rejected?
Which Position Mode were you in when you logged the RINEX? Static or Rover? You probably need to be in Rover mode while you’re collecting RINEX data for post-processing.
Your rate is 1Hz. Both CSRS and OPUS expect an interval of 30 seconds. Perhaps that’s the issue?
If you Private Message the file to me, I will take a look at it. You may need to add the filename suffix “.txt” before you can attach it.
Best wishes,
Paul
Hi, Thanks for reaching out. The service is Kinematica. I believe the message about the file was something like antenna mismatch or unknown antenna. The RINEX files I successfully submit from other base stations are at 1hz and that is what is required for our application.
Hi @Agcopter ,
Thanks for the quick reply.
I’ve got zero experience with Kinematica, so I may not be much help here.
It would help if you could copy and paste the error message. It may give us more clues.
If Kinematica does not recognise the SFESPK6618H antenna type, could you perhaps try entering an antenna type that has worked for you in the past? The results won’t be completely accurate, but at least it will identify if the antenna type is the issue.
And / or submit the file to CSRS (NRCAN) and see what that makes of it.
I assume your antenna was stationary while you were collecting data?
Best wishes,
Paul
Thanks for sending the RINEX file.
It contains GNSS NAV DATA. It’s a NAV file, rather than an OBS observation (OBSERVATION DATA) file. Is that expected?
What’s your objective? To post-process the position of the antenna? Using ‘Base’ corrections from Kinematica?
Best,
Paul
Sorry I sent the wrong file. I have now sent you the observation file. I think the issue is that as is shown in the graphic above. It doesn’t identify an Antenna ID (unknown) and under Antenna Type it shows SFESPK6618H and then says Unknown
No worries. Thank you.
I’ve uploaded your file to CSRS. That’s probably the quickest way to make sure the file itself is OK.
RINEX files are plain text. You can edit them - if you are careful. Line 8 contains the antenna details:
Unknown SFESPK6618H NONE ANT # / TYPE
Maybe you could try pasting in the details from a successful OBS file - with a known antenna?
Be careful to preserve the space alignment. The first letter of the antenna type needs to line up with the “S” of “SEPT” on the line above. And make sure you preserve the extra spaces on the end of the line. Each line should be exactly 80 characters wide. The dots are spaces in the image below:
I will PM the CSRS results to you.
Hi @Agcopter ,
I found another way to set the Antenna type and Serial number (Antenna ID) settings:
Via the X5’s web page (192.168.3.1 if you are connected on Ethernet-over-USB):
Open the Admin \ Expert Control option and click Proceed
Click on Control Panel and navigate to Navigation \ Receiver Setup \ Antennas:
You can set the Antenna type to “Other” and enter your own value if needed
No reply from CSRS yet… It can sometimes take hours for the report to be returned.
Hope this helps,
Paul
