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?
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.
With Version 3.2 came Multiple Signal Messages, which combined “messages together with associated data instead of sending separate messages to accomplish the same task.”
Message 1230 communicates the GLONASS Code-Phase Bias (CPB) information. This information allows RTK rovers to compensate for differences in biases between themselves and the base station, enabling or improving the resolution of GLONASS ambiguities.
CPB values for all GLONASS FDMA signals available in the data stream of both MSM and Legacy (1081-1088 and 1009-1012) are mandatory for full GLONASS interoperability."
Emlid’s REACH M2 is using RTCM-3.2, and if MSM4 is being used, then 1230 would not be needed, if the above cite is true ( available in the data stream of both MSM).
