Multi-constellations?
Ok, I recently bought a Carlson BRX+6 base/rover and am about halfway round the learning curve. My question is whether there is an advantage of sometimes not tracking all of the available constellations?
Thanks

There is NO advantage to tracking fewer constellations. More is better. More constellations is better. More satellites is better.
There is the possibility that if you have a constellation with 3 or fewer healthy satellites being tracked, some software may get wrapped around the axle trying to resolve that data – I suspect that all GPS software these days would recognize the issue and just wouldn’t use that constellation.

In my experience, no.
I have had maybe two or three incidences of a rover failing to fix/stay fixed, and turning off GLONASS cleared up the issue. I believe it was a bad or missing ephemeris file. But that is not what you are asking.
I guess tracking fewer constellations at both base and rover means less information being transmitted in the correction message by the UHF radio, which means longer battery life…
