Looks like a real crowd up there:
- two birds with the same PRN (#1 in B6 and #1 in D6)
- two birds at the same slot (PRN5 in E6 and PRN10 also in E6?)

(Yes, I know, http://www.navcen.uscg.gov/?Do=constellationStatus
claims that PRN 10 is at E13... far, far away from E6)

Who manages this data? Navteq?

What a mess

USCG Navcen has takes weeks to update some of the information. For
instance, even though SVN49 isn't broadcast L-band for over a month,
it's still showing on their board (without any NANU link, so and
uninformed user would think SVN49 is healthy broadcasting PRN1). When
SVN62/PRN25 was launched, it took them about one month to add it to
the board. I suggest using:
http://earth-info.nga.mil/GandG/sathtml/satinfo.html
or
ftp://tycho.usno.navy.mil/pub/gps/gpsb2.txt

And for NANUs
https://gps.afspc.af.mil/gps/archive/2011/NANUS/

The NGA site updates some stuff ahead of it happening (as planned
action) and the USAF NANU site updates in real time (I think it's the
hot page for that data).

I noticed it. I was joking

It's not difficult to distinguish correct information from
incorrect one, but it is funny to see such errors. As Germans
would say, "schlamperei".

Maybe I'm too optimistic when I expect that people (whose job is
conected with a system such as GPS) are trying to do their job
well and accurately, just as satellites and GPS receivers do.
OTOH, no one is perfect

Particularly disturbing is I sent e-mail to USCG navcen, asking them
to rectify the obvious back when SVN62 was launched, to no avail. It's
like there's no brainpower behind those responding to the e-mails...
Better not having those pages at all if they can't be trusted. That
should go without saying. What's obvious to me and you might not be
obvious to someone without any GPS education...

Perhaps posting here might hit somebody's nerve. Not to make somebody
angry, but to effect change. Too much government = bad (as well as too
little government).

I've also noticed the Operational Advisory persists to contain an
entry for the defective SV49 although it has been decommissioned and
removed from the broadcast almanac. I'd contend reference to
satellites that are currently in commission should appear.

Then there are issues related to the 24+3 configuration. I've seen
reference to the expandable slots being designated by A (Aft) and F
(Forward) but the Air Force system operators have used designations
like 11, 12 to describe expandable satellite positions. Currently,
every satellite has a standard position designator. I'm doubtful
there is any real attempt to describe the real configuration in an
Operational Advisory.

Perhaps the system operators will 'clean things up' when GPS IIF-2
begins sending PRN01.

The DoD doesn't respond to questions from the public concerning
operational matters. But, some time ago, there was a call for public
comment on future constellation reporting because standards will be
altered many years from now when OCX is implemented with Block III
satellites.
