So the fact that you see those means you're getting SBAS corrections from
one of them, but the driver doesn't pass out the information about which
one.

Bot the fact that I see *two* diamonds on the screenshot actually
worries me a little.  The UBX chip and driver only retain coverage info
for one SBAS sat at a time, which implies that one of those two is
being seen as a conventional GPS sat despite the high PRN.  I don't
know if this is expected or a bug.

I am pressing F5 repeatedly, I will send you a screenshot with both filled in :-)

Would it help that both 129 and 137 are from the same system (MSAS), so might be broadcasting *exactly* the same info?  MTSAT 1R (129) is way past expected end-of-life.

I am well outside the coverage area for the SBAS of MSAS; it is supposed to be between 25N and 45N, and I am on the equator; plus I am significantly west as well.  I am not complaining, just concerned that we have a bug.

I shall try with the GR-801 which is supposed to be on its way from Navisys, and report back in a week.
