Facet. Elevation mask in base mode
Hi, yesterday it seemed to me that the elevation mask defined in Facet’s settings only works in rover mode.
It had no effect in base mode.
Could you please check this? I’m very interested in removing satellites with low altitude above the horizon in base mode.
Thank you.

I don’t think it really matters for a Base (but I’m not absolutely sure).
The Base is sending it’s Observation Data to it’s Rovers.
A proper Elevation Mask setting in the Rover will cause the Rover to ignore that Satellite anyway.
I don’t think the Base’s Elevation Mask will have an impact on the RTK solution.
Again, I’m not absolutely positive - so I’m interested in what others say also.
In principle, I agree, but since I’ve been having problems with Facet blocking when transmitting via ntrip, I’m trying to reduce the data load.
If I set a mask of, say, 10 or 15 degrees, I eliminate some satellites and the data load to be transmitted decreases.
Ah, I get your point. Thanks !
As noted it will diminish the amount of data moved, and represents the furthest distance to the satellite on it’s transit.
RTK will use a common subset of satellites visible at both ends, so exclusion at either end should be sufficient.
If there is carrier signal lock, and ambiguity resolution, the data might remain sufficiently valid as the satellite drops below the elevation mask. The maximum number of satellites in a solution might also provide for a way to select/limit the best to use.
Depending on the application, I’d probably tend to have the base broadcast all available details, and let the rover decide if the measurements are the outliers or aberrations. The carrier phase containment should get you into the sub-mm realm
