I was excited when I found out about this service, but it seems to not be talked about? To me, that means it's working great and no hiccups to post about or it bombed and nothing has improved?
Is JCORS a viable solution for those of you using it? Is it free to try?

I've taken it for a spin a time or two. It works ok for the most part.
The latency is pretty unacceptable, though. Could just be where I am, though I don't have a problem with other services (including setting my T3 up to transmit corrections over UDP to a VPS where I have it port forwarded to a TCP service to which I can connect my LS+ ... that yields very good performance).
There's also an issue where, if you change/delete the "default" auto-created NTRIP mount point, it is impossible to re-create it. I poked around at it once, it broke, and I've never been able to use it again regardless of the approach I take to do so. No great loss due to the aforementioned performance issue, but it would be nice if I could revive it somehow to continue testing...

Any updates?

Interesting: (including setting my T3 up to transmit corrections over UDP to a VPS where I have it port forwarded to a TCP service to which I can connect my LS+ ... that yields very good performance).
Can you explain the setup (hardware, software, etc) you use to accomplish this?

1 I don't know what's going on at javad.
2 Ukraine Russia stress, is stressing somebody.
3 I'm sure that some of the previous people who could help, are otherwise occupied.
4 maybe somebody will step foreward, and this "in the dark" situation will be remedied.

I heard awhile back that all Russian staff were in the U.S., but that's just hearsay.
My guess is that the disarray is due to Javad's untimely demise - recovering from the loss of a visionary (and undoubtedly polarizing) leader is no easy feat. I hope his successors can pull it off.

We have been using JCors off and on since it was implemented.
Most of our surveys are within range of the 1-watt, but in December 2022 we had two large areas and used the JCors on 15 days. We used both LS units off the one mount point. We run off cell phone hotspots. We were hoping to connect our RTK drone to our T-3 base, but it appears that the supported units have to be Javad registered.
I have been thinking that the engineers have been focusing on the development of the new units and firmware, I have been somewhat surprised that the 7LS participation here has seemed to have fallen off though.

Thanks. I put in a request for one of the engineers to log on and take a look at my unit earlier this week and it stayed connected to RAMS for a day and a half uninterrupted. Not even a reply yet to help.
I don't even know who is still working there that we used to have very good interactions with? I'm willing to bet that the people in charge of decisions at Javad prolly don't peruse this user forum like Mr. Javad used to. I really felt he was in touch with us end users. I really miss that.
JCORS is still in the development phase and is there to be used if you are able. Some users may have trouble receiving the email that is sent during registration. Others have no issue at all. JCORS can go down periodically for a number of reasons. So, use at your own risk. The engineers will get back on JCORS when time allows.

Adam,
Thank you for the response and I appreciate the update. I will give it try to see how it goes. Sure is a great feature.
A JAVAD 'base' with an Internet connection can be setup as an NTRIP Caster.
Thus replacing the need to provide JAVAD 'base' TCPO corrections to the original / development phase JCORS NTRIP server service via the Internet.
The JAVAD 'base' NTRIP Caster option (OAF configuration) allows for multiple 'mountpoints' so as to provide various RTCM correction message types in parallel for various 'remote' user requirements, from one JAVAD 'base' GNSS receiver.

That is great. Can you elaborate on how this can be setup? Is this in Netview?
1) The NTRIP Caster OAF Configuration option needs to be activated on the JAVAD Triumph 'base' unit.
2) Then with a JAVAD Triumph 'base', setup with a 'static' IP-Address (to access the Internet), configure the NTRIP Caster networking parameters (I prefer to use NetView).
See the image for an example configuration.
3) The JAVAD Triumph 'base' NTRIP Caster can then be accessed over the Internet using the 'static' IP-Address and the TCP Port 2101, and entering the correct 'Username' and 'Password', then selecting the required 'mountpoint' to be used.

Also: Remember to setup the correct JAVAD Triumph 'base' reference position ARP / APC values (and save).
Plus update the NTRIP Caster 'mountpoint' latitude and longitude information (and save).
For Internet connection access using a Static IP-Address.
a) If using a JAVAD Triumph-1Mplus or a Triumph-3 'base' installed with a cellular SIM card (with a Static IP-Address), then the 'ports' required
to be available to/from the Internet are available (should not be blocked).
b) If using a JAVAD Triumph 'base' with local network 'Router' or 'Wi-Fi' or 'hotspot' connection, then the 'ports' required to be available to/from the Internet
must be enabled using 'Port Forwarding' (on the local network 'Router' or 'Wi-Fi' or 'hotspot' device).
