They are all independent units. So they all have their own antennas/coax/etc. Power was not an issue either.
I am not familiar with RAIM, but if it costs more, I don't have it. All three were also different makes/models. Once the signal was lost, it went into "sky scan" mode and didn't pick up any birds.
I can't see it being interference, or the GLONASS birds would probably have disappeared as well.
I am getting DGPS signals here, so there is correction.
Fortunately I was at anchor and it wasn't too big a deal, but just a bit strange. It isn't so much the loss of positioning, it's the fact that a loss of GPS on here means the loss of comms gear and endless alarms from various equipment.
