I had a similar problem to the thread below when using RS3 on my own SNIP Caster.
After a few days of troubleshooting, it turns out that I had to filter out RTCM1033 message to prevent the RS3 from jumping back and forth between fix and single every 10 seconds.
Hopefully some of you will find this hint useful and perhaps EMLID can provide a fix for emlid flow soon. This problem does not occur with my other non-emlid receivers.
We’d like to investigate this issue further. It’d be helpful if you could trigger this behavior once more and generate a Full System Report. Also, which NTRIP service are you using?
