RS2+ as Ntrip base for Trimble

[Hawkins]

Hi, I am trying to use and RS2+ as a RTK base station for some Trimble Receivers (R2,R10). I have got this working well except for the Galileo system. RTCM Messages I am sending from the RS2+ are 1006,1074,1084,1094,1124,1230,1008 and 1033.

Message 1094 is the Galileo message, and I have used snip to understand what is different about the Emlid 1094 message and other services I have access to. The only difference is that the codes L1C and L7Q for Emlid and L1x and L5x for others

Is it possible for Emlid output the 1094 message with the L1x and L5x code?

Attached are some screenshots

Hi! I also have the same problem that I wrote about in this forum thread. Look at this information, maybe it will help you.

Emlid caster, Rs2 messages Rtcm

Why message 1230 is not sent via Emlid caster, although this message is enabled in Base settings in Rs2? I check received packets from caster using Ntrip checker. Ntrip checker shows all messages that are enabled in base settings, except 1230. I also check the stream from the Cors system, 1230 is also enabled in their stream and ntrip checker sees it. What could be the problem and how to solve it? Due to the fact that this message does not reach the rover, some Gnss receivers do not receive …

Emlid promised to study this problem, but so far there is no answer.

Hi, yes I have had a read of your thread as well.

Can you confirm your CORS is sending the 1094 message with the L1X (E1) and L7X (E5b) codes and this is working with your trimble gear?

If this is the case then it might be the missing L5x (E5a) that Trimble require for a solution.

Our cors broadcasts these Ntrip messages, see the screenshot. Trimble works without problems from it.

Hi guys,

The L5X code refers to the Galileo signal in the E5a frequency band, while L7Q corresponds to E5b. Our Reach receivers can only track the E5b signal (L7Q). This is why, if Trimble indeed requires the E5a signal for the calculation, Galileo satellites from Reach RS2+ would not be considered. Due to hardware limitations, we can’t update the existing devices to support E5a. However, I’ve shared your use case with our development team for future reference.
