Fellow time-nuts,

Things will shift in the sky. Lot's of changes.

SVN-33 is being decommissioned after 17.5 years of operation, with a 7
years designed lifetime, that's 2.5 times the operational lifetime, and
it's being decommissioned in a controlled fashion. Respect.

Cheers,
Magnus

The Air Force is set to launch the 7th GPS IIF satellite from Cape
Canaveral Air Force Station in Florida.

Delta IV GPS IIF-7 Mission Overview:

Atlas V GPS IIF-7 Mission Brochure:
http://www.ulalaunch.com/uploads/docs/Mission_Booklets/AV/av_GPSIIF7_MOB.pdf

Rocket/Payload: An Atlas V 401 will launch the GPS IIF-7 mission for the
U.S. Air Force.

Date/Site/Launch Time: Friday, Aug. 1, 2014, from Space Launch Complex
(SLC)-41 at Cape Canaveral Air Force Station, Fla. The 18-minute launch
window opens at 11:23 p.m. EDT.

Viewing the Launch by Webcast: The live webcast will begin at 11:03 p.m.
EDT.

GPS IIF-7 is one of the next-generation GPS satellites, incorporating
various improvements to provide greater accuracy, increased signals, and
enhanced performance for users.

Launch Updates: To keep up to speed with updates to the launch countdown,
dial the ULA launch hotline at 1-877-852-4321 or join the conversation at
www.facebook.com/ulalaunch and twitter.com/ulalaunch; hashtag #GPSIIF7.

The Air Force Second Space Operations Squadron indicates that IIF-7,
SVN-68/PRN-3, will replace SVN-43 in the F plane slot 3 (F3).  SVN-43 will
be re-phased from F3 to the F2F slot to replace SVN-26.  SVN-33 will be
taken out of the operational constellation the day after SVN-68 launch and
sent to Launch, Anomaly and Disposal Operations (LADO).  SVN-33 was launched
on 09 April 1996 successfully serving over 17.5 years, 10.5 years beyond its
design life, due to the diligent efforts of the men and women of the U.S.
Air Force. SVN-26 will back-up SVN-43 once it completes its re-phase
journey.

Hi Magnus et al - just FYI: 2 1/2 times the design lifetime is not unusual
for satellites.  More of the Ham Oscar satellites have exceeded their
lifetime by that much or more.  (Sorry, no facts handy).

It saves us USA taxpayers money when they last that long!

John,

It has delayed the launching of birds, as the old ones does not die of
quick enough for the planned schematic to maintain 24 birds, instead we
see 30-32 birds active for many years, and some being "off air" backups.

On the other hand, it gives more time to adjust the new birds with new
signals.

Cheers,
Magnus

Lasting longer should be no surprise.  The design spec in years is NOT
the mean time before failure.  It is more like the 4-sigma time before
failure.
It is so far out there that many times what kills them finally is
running out of propellent.      "Design lifetime" is kind of a
misleading term.
