LIVE: Atlas V 401 - GPS IIF-7 - August 01, 2014
« on: 02/21/2014 06:08 PM »
This is going to be the third GPS launch in just half a year!

Here's another excellent article from William Graham covering this mission.

As GPS IIF-5 is SVN 64, and SVN 65 and 66 were already taken by GPS IIF-3 and 4, so GPS IIF-6 should be SVN 67 and GPS IIF-7 should be SVN 68, which is just a wild guess.

Predict PRN3, secondary possibility PRN8.

There is also possibility for PRN4, which was assumed to be take by GPS IIF-6; but the just launched IIF-6 already took PRN6.

Removed the first post, my logic was incomplete and likely wrong.
PRN 3 / SVN 33 will likely be shutdown to free up almanac space.
Once PRN 3 is shutdown, PRN 3 and PRN 9 will be available for assignment.
Based on past behavior, PRN 9 will be assigned (the one that has been offline the longest).
My real bet is on what GPS IIA will be shutdown to free up almanac space.

There is almost zero chance PRN 4 or PRN 8 will be decommissioned instead, since they are replaced by IIF-5 and IIF-6 both of which are still in checkout, and they typically wait until it's operational for a good time (say 6 months) before becoming first choices for shutting down the satellite it replaced.
Even if IIF-7 gets delayed by as much as two months, the prediction stays the same.

It has been common to keep 3 satellites doing the job of 2 paired orbital slots.
PRN 3 replacement SVN 66 / PRN 27 has been operational since 06/21/2013.

The comment from NGA doesn't make much sense, since IIF-6 is replacing PRN 4 / SVN 34. But PRN 4 should stay online until IIF-6 completes its checkout and is set healthy for a while before SVN 34 gets shutdown (probably for IIF-9 or IIF-10)

NGA is probably more authoritative than most of people in this forum. Your statement on GPS IIF-6 uses PRN 6 is definitely wrong - it is using PRN 6 and its signals have been tracked by many receivers around the world.

Yes IIF-6 is broadcasting using PRN6, that's correct. But what you don't get is that its broadcasting an unhealthy signal, and it will take at least about a month its checkout period testing to be completed, only after the checkout is complete the satellite will start broadcasting a healthy signal. Until healthy, the satellite should only be used for the express purpose of testing the satellite.

Even after IIF-6 is set healthy, the observed procedure is to keep the new and the old satellite broadcasting for many months (over a year when possible).

PRN 30 (SVN 64) replaces PRN 8 / SVN 38 and PRN 9 / SVN 39. The latter is already decommissioned, but the former should stay online for many months AFTER SVN 64 is set healthy (USABINIT NANU).

PRN 06 (SVN 67) replaces PRN 4 / SVN 34. As I explaned, SVN 34 should be kept operational for many months after SVN 67 is set healthy (USABINIT NANU).

I my lingo, a GPS satellite is not operational until it's set HEALTHY, right now SVN 64 and SVN 67 are broadcasting an unhealthy signal, so it's not operational (only special receivers set to track unhealthy signals are even capable of tracking those signals).

I my lingo, a GPS satellite is not operational until it's set HEALTHY, right now SVN 64 and SVN 67 are broadcasting an unhealthy signal, so it's not operational...
SVN 64 was set healthy on May 30.

Since it hasn't been stated yet, I'll pick a fight and start the arrows headed my way... Here's the first launch of what we now know may now turn out to be a finite number of Atlas 5/RD-180 cores with a payload that is ALREADY Delta IV qualified.  In several years a payload requiring an Atlas 541 or 551 may be seriously delayed because the RD-180 was "wasted" on a GPS satellite fully capable of riding an RS-68...

"...the first launch of what we now know may now turn out to be a finite number of Atlas 5/RD-180 cores with a payload that is ALREADY Delta IV qualified..."

I would call this the second.  GPS_IIF-04 (a.k.a. Navstar-066, a.k.a. USA-0242, a.k.a. Vega) was launched on an Atlas-V(401) after three consecutive successful flights of the GPS_IIF on Delta-IVs.  The number of RD-180s has always been, and will continue to remain, finite!   :-)

USA-242 was launched on 15 May 2013, long before there was threat of the RD-180 supply being cut off and ULA could blissfully "waste" an awesome, cheap engine to launch a payload that didn't require it because there was an endless supply.

The real issue should be: Is this launch needed right now for constellation sustainment ?
The answer is not really. The GPS constellation as of right now is better than ever.

Another question, would the cost of storing those satellites on the ground be higher than launching them: Perhaps

Launching IIF-7 and IIF-8 makes some technical sense as they clean up the way to launching IIIA-1 when its ready (fulfilling the 24+3 orbital layout even with all GPS IIA birds retired).
But launching IIF-9/10/11/12 as scheduled makes increasingly less sense (regardless of which booster is used). While ground storage costs money, latter launch would extend the service life of those satellites.
All GPS IIF satellites should still be serving us past 2030, with most of the lasting past 2040 and some all the way into 2050.
What if there is a major problem with IIIA satellites ? Having a few IIF on ground storage gives flexibility to launch them on more pressing orbital slots in the future should anything unplanned happen.
GPS satellites don't die sequentially. Although they provide quite a bit of early warning, having a strategic reserve of IIF satellites on the ground until the first IIIA is fully tested is a wise move (that isn't contemplated in the current GPS launch planning).
There is a lot of bureaucratic inertia in the GPS constellation sustainment process.

I think clearly the cost of X years of storage plus a launch in year X+1 is higher than a launch in year 1, unless the cost of launch in year X+1 is enough lower than the cost in year 1 that it covers the storage cost. So Jim is likely right, because launch costs are not likely to come down. Ever. No matter what happens. :)

But I don't think that's the right question.  The right question is to ask what is the total cost of ownership of the entire GPS constellation (as birds die and get replaced) over the next N (where N is some large number, say 50) years.  And I think there the argument can be made that IF you have sufficient on orbit spares already, why launch another spare now? Assuming the on orbit life is not diminished by storage, launching way more birds now than you need means you need replacement birds sooner and your TCO goes up.

It costs more because all the IIF spacecraft are built but the design and build team has to be maintained until the last of the series is on orbit.   The USAF operates the spacecraft on orbit and so the required support from Boeing is much less.

Right now, the USAF is paying for two separate design and build teams; IIF (Boeing) & III (LM)

Macpacheco, weren't you the one saying that they were not replenishing fast enough and should increase the rate?
Its true that a faster launch pace will speed up making L2C / M-Code signal operational.
But the really critical signal, L5 (essential for a complete migration from ground based navigation to satellite based navigation, specially retirement of billions USD worth of aging+obsolete ground equipment), is still 18 launches away from being operational, requiring all ordered GPS IIIA satellites plus a bunch of not even ordered ones.
I was consistently whining back when not even one launch / year was being executed, but on the other hand 3 or more launches per year is a waste of money, unless the plan is to launch a few more and stop for a few years.
Launching new GPS satellites too fast equals wasting perfectly good IIR GPS satellites. Lets get rid of the IIAs, those are really old and are performing much worse than the rest of the constellation.
But after launching IIF-7 + IIF-8 the constellation should have 27 healthy birds even with all IIA birds retired. Performance spec is for 27 birds.
The sweet spot is two launches per year.
It's a juggling act (conflicting priorities) between sustaining the constellation and preparing for M-Code/L2C FOC (and future L5 FOC).
The main GPS challenge right now is getting OCX fully operational and the first IIIA launched. Both projects are facing delays and (F35 like) SNAFUs.

They could also be planning on using the upper PRNs if needed for the GPS IIIA birds, and both exceeding the performance specs and giving themselves more on-orbit redundancy (I imagine they weren't happy with that GAO report from a while back).

But this has drifted to general GPS policy instead of mission specific (I don't think there IS an active general GPS thread...).

There are two bottlenecks to use the upper PRNs:
1 - AEP have a 31 PRN almanac limit
2 - AEP can't assign PRN33-PRN36
OCX block I remove both limitations.
But OCX can't manage IIA GPS birds, one of the reasons another 2 launches are very important (pave the way to have all remaining IIA GPS decommissioned for OCX block I activation)
With IIF-1 ... IIF-8 healthy, there will be 28 IIR+IIRM+IIF birds in orbit, minus SVN49 that has that L5 test payload problem, leaves 27 healthy birds, just enough to produce a 24+3 compliant constellation layout even with all GPS IIA retired (enabling OCX activation)
Plus without OCX block I online, IIIA GPS can't be fully managed (can't be added to the almanac nor can be set healthy)

Thanks for clarifying that, I hadn't thought about the support team aspect and reducing dups... What is the burn rate (yearly cost) on (each of) the teams, do we know off hand or is that proprietary?

Does anyone know the Atlas/Centaur tail number for this launch? AV-0xx ?

One website is reporting AV-048 (047 for Worldview 3?).
At what point do we stop using those designators if there actually are no more "tail" numbers on the vehicles themselves and if ULA does not use them in its press materials?

Because they are used in all engineering documentation.  OV numbers were not "on" the vehicles visible to the public.  There is a parts tag on the vehicle that does say AV-XXX.  T

But that is the problem.  By "we" I mean those of us outside the program, who don't see the engineering documentation.  "We" have no way to identify these vehicles.  If "we" start guessing, "we" are eventually going to get it wrong, which confuses future historians.  Better, I think, to stop guessing altogether.

Much appreciated, but still second-hand for those outside the gate.  I would like to see ULA provide the information directly.

The satellite (SVN68) will be launched into slot F3 to replace GPS IIR-2/SVN43 (launched July 1997); which in turn will be moved to slot F5 to replace GPS IIA-14/SVN26 (launched July 1992; 2nd oldest GPS satellite currently in service).

Interesting.  The star Capella, means 'Little Goat', and the goat is the animal associated with the constellation Auriga.  The ULA mission patch, therefore, is a bit of an anomaly, and my question is simple:  which goat at ULA doesn't know the difference between a GOAT and a SHEEP (ram)?!?!  The constellation associated with sheep is Aries, but Capella is not in Aries....

I'm just sayin'....

None of these are ULA patches.  They are USAF patches.
The top one is the 5th SLS and bottom one is the 45th LCSS.

Per ULA, due to constant delays with the Delta IV launch, this launch will slip to August 1 local time (August 2 GMT - should be 03:23 - 03:41 UTC IIRC).

The Delta IV LOX and LH tanks are covered in foam. The Atlas V first stage LOX tank is not. So you should have greater amounts of LOX boil off.

hmm interesting the Altas seems to have more lox boiloff than the Delta iv.

Wonder if that's true or if its just weather conditions?

The Delta IV LOX and LH tanks are covered in foam. The Atlas V first stage LOX tank is not. So you should have greater amounts of LOX boil off.

Boil off does appear to be more than usual for Atlas V, not that I've seen most of them.

Heh. There's the now well known solar radiation call on the loop.
btw. There where two M class solar flares earlier today, and a minor CME impact. So was a worthwhile check.
If you're happy and you know it,

7th Boeing GPS IIF Delivered to Orbit and Operational

Third launch this year in Boeing-Air Force GPS modernization effort


CAPE CANAVERAL AIR FORCE STATION, Fla., Aug. 2, 2014 – A Boeing [NYSE: BA] Global Positioning System (GPS) IIF satellite, launched late yesterday, has sent the signals to controllers that confirm it is currently operating properly within the constellation that millions of people rely on for timing and navigation information.

GPS IIF-7 was launched aboard a United Launch Alliance Atlas-5 rocket from Cape Canaveral. It is the seventh of 12 such satellites Boeing has built for the U.S. Air Force, and the third on-orbit delivery this year.

“We are providing our Air Force partner and GPS users with a steady supply of advanced GPS IIFs,” said Craig Cooning, president of Boeing Network & Space Systems. “Our robust launch tempo requires vigilance and attention to detail, and mission success is our top priority. We continue to partner with the Air Force and ULA to effectively execute the launch schedule.”

Boeing and the Air Force will complete the full on-orbit checkout of the satellite next month. The GPS IIFs offer improved signal accuracy, better anti-jamming capability, longer design life and the new civilian L5 signal.

GPS IIF-8, slated for launch during the fourth quarter, arrived at Cape Canaveral on July 16 to undergo final launch preparations.

Congrats to all teams.

Apt that the launch marking this change should be a GPS one.

WASHINGTON — The successful launch Aug. 1 of the U.S. Air Force’s seventh GPS 2F navigation satellite from Cape Canaveral Air Force Station, Florida, marked the final time the service is expected to rely on C-band radars to track rockets immediately following liftoff.

Future Air Force launches, both from the Cape and from Vandenberg Air Force Base in California, will rely on GPS signals for post-liftoff tracking, service officials said. The Air Force and its primary launch services provider, United Launch Alliance of Denver, have been working for years on the capability, which features rocket-mounted GPS receivers that transmit position-location data to controllers on the ground.

The article is in error - AV-047/Worldview 3 will fly a transponder, not GPS-MTS.

Is that actually the last flight to do this?

But was AV-048 the last one to do so from the Cape?

I think so, but I haven't yet seen the installation data for AV-049/CLIO. IIRC, there are two transponders in ULA inventory, one of those assigned to AV-047, of course.
