Hi, back and after some specific advice again!
Does anyone have experience of using the Trimble SPS855 as an NTRIP caster.
I am using the web interface and it claims to be able to enable 3 NTRIP casters each supporting 10 users.
I have managed to receive corrections by radio, and also by IBSS (NTRIP caster via Trimble Connected Community).
The IBSS method is a bit buggy and requires a TCC device login for every device.
I would like to use the NTRIP casters if possible but I cannot get it to connect.
I have created a login with "NTRIP caster" ticked.
The other settings on the SPS855 are as shown below.
I am trying to connect by Trimble Access. It will connect by IBSS (2 or 3 trys required) or by radio so I have the settings in Access right I think.
Maybe there is something I am missing, or it just doesn't work properly!
Ok, I have discovered that the network router is not forwarding the inbound connections - or to be exact it is doing so sometimes, but inconsistently.
Unfortunately I will have to rely on the superior humanoids in IT to sort this. I will not hold my breath!
Now have this fully operational as GNSS base station broadcasting on the internet.
Needed a fixed IP SIM card on the attached 3G modem. Even with DynDNS, the IP address shown by the 3G network using a regular SIM card was not private, but shared between many users somehow.

I got it to work quite reliably on an R10 over the built-in sim card modem. I had to get a fixed IP, and I often set it up wherever and fire it up as a base. When I tried to get it working on my internal office network, I could access it from inside (i.e. local IP) but not from outside. Once I got the sim card working, I never tried the office network again. AT&T made me get a 5 GB/month account, so I have plenty of data to use without ever going over the limit. Verizon did the same with the rtk bridge I have (5 GB). I wonder if the providers in GB make you get a large data package? I am not sure why I cannot get a much smaller (and cheaper) package, but I was told that was the "machine-to-machine" package they offer.
Update: I hadn't tried to access the R10 over the office network from outside since January. I just set it up now on my test pillar, turned off the internal modem, and connected it via wifi. I am now able to access it from outside, using both a name and an IP address. Not sure why it works now and not before, but I definitely know a lot more about it now. I have an ntrip client on my android phone, I use that for testing connections. At lunch time I will try to access it using an R8 and a dc from outside. Usually I access it by the fixed IP address on the sim card, but it does have a dynamic DNS update feature that I will try so that I can access it by name rather than IP address. That way it should work seamlessly inside the office network or outside on cell.
I just tried the DDNS, and it does update the DNS tables (I use no-ip), so it should work from now on using the name wherever it is.
Interested in your android ntrip client John.
What is the name and where can I get it?
@squowse
I have a SPS855 and am trying to create a NTRIP server / caster.
Could you please help me with the process?
Do I have to create a NTRIP Server or Caster?
Do I need a SIM Card? with Fixed IP?
?ÿ
Thanks a lot!
