D Ninja writes "Yesterday, Lockheed Martin was awarded the $1.4 billion Air Force contract to build the next-generation global positioning satellite system. This occurred after a series of delays as the Air Force decided between Lockheed and the competing bidding contractor, Boeing Co. 'GPS III, will give new navigation warfare (NAVWAR) capabilities to shut off GPS service to a limited geographical location while providing GPS to US and allied forces. GPS III will offer significant improvements in navigation capabilities by improving interoperability and jam resistance. The procurement of the GPS III system is planned for multiple blocks, with the GPS IIIA portion currently underway. GPS IIIA includes all of the GPS IIF capability plus up to a ten-fold increase in signal power, a new civil signal compatible with the European Union's Galileo system, and a new spacecraft bus that will allow a growth path to future blocks.'"
This AC would be the prime example of an oxymoron. - While im here it was NGS not NVS (Northrop Grumman) FTFA which I clearly did not read until just now
The loss is Boeing's fourth straight in three months on a US defense contract valued at more than $500 million. Boeing lost to Northrop Grumman on a $US35 billion Air Force refueling tanker aircraft contest in February and a $US3.74 billion Navy unmanned spyplane order in April. Lockheed beat Boeing for a $US766 million radio contract in March. Northrop's partner on the tanker contract is the parent of Toulouse, France-based Airbus, Boeing's only bigger rival in commercial planes.
Why didn't they have NASA build it? They're not for profit and always want more money to do stuff. Any company is obviously making money off it while NASA wouldn't be. Plus, they kinda know a bit about space and satellites.
You do realize that NASA is a hell of a lot like the Air Force, they pay a bunch of contractors like Lockheed to do most of the work? NASA isn't interested (and has no authority over) the warfare parts, they have very little that's classified by way of personnel and information, so it's a job much more suited to the Air Force, what with the NAVWAR and other capabilities they think it needs.
Lockheed also knows quite a lot about space and satellites. They built the satellite that the Hubble is housed in. They built the rocket upper stage that the Gemini went to space in, they built the Corona series spy satellites, and they built the Atlas V rocket. I'm sure there's more. As someone else pointed out, NASA generally doesn't build stuff. They contract out most things. Because paying companies who want to make money happens to be an excellent way to get stuff built.

Actually, no, that translates to "GPSIII receivers can also receive Galileo signals so GPS doens't become obsolete". Galileo's public version is as accurate as current military GPS, and Galileo's commercial version is approximately 10x more accurate than current military GPS. In other words, as Galileo grows, less and less people would have any reason to continue supporting GPS.
If you think anyone in Europe would trust US military programs or give the US any control over european satellites after the Bush junta, you must be out of your mind.
If you think anyone in Europe would trust US military programs or give the US any control over european satellites
The US military has enough control over every satellite to turn it off, regardless of popular opinion in Europe. If the US wants Galileo turned off, then "launch launch launch pop pop pop" off it goes. It's ridiculous to think that the Galileo program was somehow a counter to the US military.
OK, here's a hypothetical situation for you. One of the major EU countries wants to engage in military action, but the U.S. is against this.
This sounds a bit far-fetched at first... if there's a conflict and it's sufficiently serious that the Europeans want to take up arms, wouldn't the U.S. want a piece of the action? But perhaps it involves a terrorist attack on an EU country, and to retaliate, the EU wants to drop some bombs or a few commando teams inside the territory of one of our close "allies" like Pakistan, where a lot of the terrorists currently hang out. But the U.S. doesn't want to risk upsetting the Pakistanis.
As I understand things, the U.S. could just say, "Fine. Go ahead. And have fun, guys... but you should remember to bring a map and a good compass, because we're not going to let you guys use our GPS system for navigation, targeting or troop maneuvers." As I understand things, the Europeans would be pretty much fucked. We could call off one of their military actions just by denying them GPS capability or degrading the signal, right?. Even if they were 90% certain they didn't actually want to use a military strike, just taking that card out of their hand would really reduce their power in a negotiation in a conflict.
In the past, I don't think this was so much of an issue. But with the fall of communism, it's less clear that the EU and US will stick together as closely as they have in the past. Furthermore, the U.S.'s foreign policy for the past 8 years, a belligerent "fuck you and get out of my way" attitude towards long-time allies like France and Germany, raises the possibility that U.S. and EU interests could come into direct conflict. Think about it this way. How would it change things if, say, France had control over the GPS system? Would the Iraq war even have been possible? The U.S. would never tolerate that state of affairs. Why should the EU?
Umm, lets start at the top. I assume you live in America. If you think France, Germany or the UK is going to invade Pakistan, well, that is honestly funny.
Also... should they decide to invade Pakistan, are you seriously suggesting without gps they cannot do it? We aren't christopher columbus, we can find countries without gps.
Further, do you realise not even US weapons use (or better put, require) gps. Scuds dont use gps + google maps to navigate. They use carefully tuned preprogrammed flight paths. More impressivly (or scarily) is ICBMS.. they have no guidance, they are shot into orbit and fall onto their targets in the km/s range with simple point and shoot logic.
I could even point out the number 3 and most relevant point... no one can seriously choose to invade pakistan. They have the bomb, the same reason as no gps / anything will cause America to be invaded, you can wipe out the earth without gps with your nukes. Its called MAD, you might have heard of it. Its americas collapse via ecconomic reasons that is the real threat... just ask the soviet union. Why does history seem to have so many lessons?:p
Incorrect. From http://www.fas.org/man/dod-101/sys/smart/jdam.htm [fas.org]
"Guidance is accomplished via the tight coupling of an accurate Global Positioning System (GPS) with a 3-axis Inertial Navigation System (INS). The Guidance Control Unit (GCU) provides accurate guidance in both GPS-aided INS modes of operation (13 meter (m) Circular Error Probable (CEP)) and INS-only modes of operation (30 m CEP). INS only is defined as GPS quality hand-off from the aircraft with GPS unavailable to the weapon (e.g. GPS jammed). In the event JDAM is unable to receive GPS signals after launch for any reason, jamming or otherwise, the INS will provide rate and acceleration measurements which the weapon software will develop into a navigation solution."
The military does not depend solely upon GPS for any navigational necessity. We had a half dozen GPS devices in my squad in Afghanistan, but we also had a map and compass and knew how to use them. It's like that all the way up to the B-2 Spirit: use GPS, but don't make it your only resource.
If you lived in the US you would know the 3 presidential candidates are basically on-record of saying they intend to MEND the relations which were damaged the past 8 years. And its why none of the US allies is alarmed - they know GWB is gone in 6 months and w/ him goes his warped policies.
I doubt it would come to this. European leaders would most likely cooperate with the US if asked, and then publicly condemn whatever is going on for the sake of the masses. And if asked nicely by a European leader the US would probably go ahead and selectively degrade GPS in some region if that were strategically necessary for a European state. While there is a lot of political posturing going on, the fact is that Europeans and Americans have a lot more in common than they have in opposition.
"launch launch launch pop pop pop" could mean the following :
1) the EU possibly starts (possibly collaboration with the Chinese) to destroy all US satellite, including KH and GPS one.
2) all intellectual property of the US are forfeited
3) the US lose ANY support whatsoever. For a VERY long time. And it find itself isolated politically, and as much isolated economically as the world can bear (I doubt there is anything the US physically produce which could not be produced/built over a few month/years in another part of the world)
4) escalation of conflict in nuclear war. Remember, some country in EU still have the same nasty nuke that you have. Then we have 2 sets of loser (EU/US) and one winner : the rest of the world.
Anybody which think that the US can kill any satellite of the EU or China because they dislike it, should have its head examinated, because there would be pretty hefty consequence.
Galileo [wikipedia.org] is going at 2 frequencies 1164 to 1214 MHz and 1563 to 1591 MHz. While it looks like (the civilian part) of this version is just centered at the (L2 = 1227.60 MHz) & (L5 = 1176.45 MHz) - so the 1164-1214 civilian GPS units for Galileo should work with the civilian bands for these satellites too. As for the military stuff.... well I couldn't say.
Do these sattelites have defences? Are their locations unknown by the enemy? No! Day 1, 0900: War Declared Day 1, 0915: All GPS satellites blasted out of the sky Day 1, 0930: US surrenders due to lack of any ability to locate their troops and organise them GPS in a military situation has always seemed to me kind of a bad idea to rely on too much. You put all this technology in your air crafts, your tanks, all your hummers, but when these precious badly defended satellites get knocked out the planes cant fly and
Name the last time the United States went to war with somebody with anti-satellite technology. When you are fighting an asymmetric battle, it is plenty useful.
Do you think the only way the U.S. can organize it's troops is through GPS? Do you think that missiles rely solely on GPS for guidance? You can't possibly think that.
Your perceived vulnerability is completely non-existent. GPS merely augments our ability to fight along with a lot of other technologies. You never rely on a single point of failure and the military practices better than most.
GPS in a military situation has always seemed to me kind of a bad idea to rely on too much.
What makes you think we are overly dependent upon them?

I'm pretty sure ground commanders have considered this issue. Hell, in the Marines when recruits were introduced to the K-Bar, a 7 inch combat knife, they were told it was the most reliable
You put all this technology in your air crafts, your tanks, all your hummers, but when these precious badly defended satellites get knocked out the planes cant fly and tanks, ships and other operations are seriously impared.
Seriously? You think we grunts don't know how to navigate with a paper map and compass? You think those planes just wandered around lost before GPS was fielded? Really, GPS is a convenience. All the shit still works without it.
The reason Europe decided to build Galileo as a direct civilian alternative to US' GPS was to prevent the US from shutting down all navigation in case of a conflict. TFA says that the new (US military) GPS now will have 500x transmit power, and also transmit a new civilian signal (L1C) to be fully compatible and interoperable with EU's Galileo.
I wonder if the capability to "interoperate" with the Galileo system also includes "Jamming". Seems like the satellite could produce a good military GPs signal while at the same time transmit a corrupt L1C signal to "interoperate" with the Galileo system.

In case of war, it won't be the US that will shut down GPS. It will be the US enemies.
Satellites are extremely vulnerable. They would be the first thing to be hit in case of a major war, this was already predicted in this thirty-year-old book [amazon.com]

A satellite's vulnerability really depends on it's orbit. Satellites in Low Earth Orbit a few hundred miles up are pretty vulnerable (as the US Navy shootdown of an errant American spy satellite recently showed). GPS satellites are in a much higher orbit, around 12,600 miles up. That makes them considerably more difficult to hit and probably puts them out of range of a lot of antisatellite capabilities (of course it's hard to tell since no country actually admits to having an ASAT weapon, much less what it's exact capabilities are). Communications satellites in geostationary orbit 22,240 are even more difficult to get to. In a war I'd be a lot more concerned about the reconnaissance satellites than GPS or communications sats.
Will this affect my driving in the future? If I'm in my car using my car's GPSIII nav and suddenly get zero signal, should I pull over immediately to 'duck and cover'?:)
It's something of a nuclear option. It's very hard to imagine any president actually authorizing this. I mean, think about it, you invade Iran or something and maybe you'd like to turn off their GPS. But nearby there are giant oil tankers being steered by GPS and airliners overhead (nearby) with GPS autopilots. Is it worth the risk of those crashing? I just don't see it happening in any situation short of a general world war.
There are still radio navigation systems such as LORAN available for ships. They aren't as accurate as GPS, but accuracy in this case means finding an airport, not finding one bolt on a chair in the airport office.
Even with GPS and Galileo and Beidou, it's still good to learn pilotage, dead reckoning, and celestial navigation. Sailing without them is similar to not knowing how to make change without the computer telling you.
We used to have "Selective Availability". That meant that the US military GPS signal was much more accurate than those found on civilian receivers. President Clinton had SA turned off worldwide meaning the civilian GPS signal is now as accurate as US military systems. Since GPS is so integrated into society now it will probably never be turned on again.
I don't think (I seldom ever do any thinking) that the current system can currently be shut off by region but SA can be turned back on regionally.
I am a little more concerned with my car being driven off a cliff by an automated traffic control system because some asshat decides to invade some other asshat, and to hell with the civilians using the system.
The insistence on a NAVWAR backdoor is rather stupid. In the last three wars in which it has been involved, the U.S. has pretty much had its rear kicked by enemies using what amounts to 1940s technology. The danger to US troops is not from WMDs, it's from IEDs made in peoples kitchens using easily obtained ordinance, generally with U.S. serial numbers on it.
If they want to blow me up, they're going to do it by setting up a bomb that reacts to the RFID in my "Real ID" card, U.S. Passport, or the pressure sensors in my tires, all of which are government mandated, and all of which go where I go, and so are really useful for targeting me both generally ("look, and American!") or personally. Or they'll use my IMEI on my cell phone, which on differs in that I'm not required to carry it, but probably will anyway.
If someone can build a missile that can get to me from where they are, then unless I am sitting in a bunker, a few hundred feet for going inertial or using airport beacons instead of GPS isn't going to matter much one way or another.

Your superiority only matters if you can use it to accomplish goals that actually further your purposes. If it came down to an all-out war between the US and anyone else, then the US would win hands down, no question. But this doesn't serve any purpose of the US -- the local and international political ramifications of obliterating another country are unacceptable, even for the most gun-ho president. And no other country is going to start an all-out war with the US, because they know they'll lose. Being able to obliterate any country in the world doesn't matter if there's no way you'd ever do that.
Being able to kick the "bad people" out of a country like Iraq while allowing the rest of the population to enjoy the economic and social benefits of capitalist democracies is absolutely something the US wants to be able to do. It appears that, as mighty and all-powerful as your military is, they're unable to achieve the actual objectives required of them.
Also, what makes you think you'd only have to kill 150 million Chinese to destroy the country? I think you're grossly underestimating either the lengths people will go to to protect their country, or the population of China.
500x more power - essentially that requires a tremendously larger amount of power. Even with the best phased array bad ass military style antennas you arent going to get this sort of a power increase - you gotta put more out of the antenna at the source - which means you are lifting honking huge freaking batteries up into space and you are gonna have to stick some mad solar panels on the sucka too. PS. I completely agree with the sentiment in your last sentence. - with that money you could probably mount a significant effort toward eliminating malaria in subtropical/tropical areas of the world, saving millions of children. Or you could provide an absurd amount of aid to prevent water born diseases in the 3rd world - or you could mount a tremendous anti-hunger campaign. Bottom line - bigger batteries on a satellite are more important to the people in charge.

I happen to have done some engineering work on GPS, and I can say that these additions are extremely non-trivial and cannot be done with existing hardware. The way the signals are transmitted must be changed entirely. The good news is that this system will allow for real-time ionospheric distortion mitigation (a problem for any non-DGPS receivers with the current system) and provide enough signal strength that even super-cheap receivers will be very accurate.
Also, this cost would likely have occurred anyway - the current satellite constellation won't live forever. The satellites will run out of orbital maintenance fuel, or their clocks will begin to drift erratically, and at some point in the foreseeable future, the constellation will lose enough satellites that it will be mostly unusable. So if we'll be launching new ones anyway, why not make them better?
I also understand your humanitarian question, however, the support that GPS provides in science and education (even though it was and is a military project in the USA) truly does humankind a great service. Oh, and it lets me find good pizza no matter where I am in the city, which is truly humanitarian:-)
Perhaps I've been in the computer industry for far too long, but how could it possibly cost 1.4bn to essentially add access control and a bigger amplifier to existing tech ?
The same way it coses $400 million to drive a remote-controlled car across a red desert?
Perhaps I've been in the computer industry for far too long, but how could it possibly cost 1.4bn to essentially add access control and a bigger amplifier to existing tech ? Will it realistically provide 1.4bn back in value, either by gaining efficiency in war planning, or enabling new civilian tech to make our lives easier ?
Because the 1.4bn is used for more than what you trivialize it to be for. The 1.4bn is for the entire contract but the initial goal is to only have 2 satellites launched with the option for 10 more. They will be integrating with the existing EU Galileo system and provides who knows what else in additional features. As one guy in the article said "'You are guaranteed a lot of business for the next 20 years. It may be enough to drive the losing competitor out of this market.'" In addition to the materials,
Turning off GPS doesn't give us any more ability to kill people. Simple keeps the enemy from killing us.
Don't underestimate the potential impact it could have on saving lives. Sure perhaps it's selfish to want to save our own lives, but hey I'm only human. If the enemy uses GPS technology to launch an attack on us we only have ourselves to blame.
Exactly. It seems silly for a military to spend all this money to gain a tactical advantage, and then leave it wide open for the enemy to use. This is the modern equivalent of blowing up your own bridges so the bad guys can't cross 'em.
I think it's an interesting problem to create a satellite that emits a radio signal that can only be used by some people, but not others, as in the "military" and "civilian" signals from these satellites.
It's really not all that hard. The civilian signal is unencrypted. The military signal is encrypted. All they do is flip a switch and the civilian signal is gone
I daresay at some point it would be considered a war crime to disrupt GPS signals, in any case, when civilization is much more dependent on them, as I think it is reasonable to expect in the future.
What? A warcrime for a Sovereign Nation to control their property?
Why do you think the EU lofted their own GPS network? Why do you think the Soviets began lofting GLONASS during the Cold War? If you don't control it, don't depend on it.

Being able to obliterate any country in the world doesn't matter if there's no way you'd ever do that.
Being able to kick the "bad people" out of a country like Iraq while allowing the rest of the population to enjoy the economic and social benefits of capitalist democracies is absolutely something the US wants to be able to do. It appears that, as mighty and all-powerful as your military is, they're unable to achieve the actual objectives required of them.
Also, what makes you think you'd only have to kill 150 million Chinese to destroy the country? I think you're grossly underestimating either the lengths people will go to to protect their country, or the population of China.

PS. I completely agree with the sentiment in your last sentence. - with that money you could probably mount a significant effort toward eliminating malaria in subtropical/tropical areas of the world, saving millions of children. Or you could provide an absurd amount of aid to prevent water born diseases in the 3rd world - or you could mount a tremendous anti-hunger campaign. Bottom line - bigger batteries on a satellite are more important to the people in charge.

Also, this cost would likely have occurred anyway - the current satellite constellation won't live forever. The satellites will run out of orbital maintenance fuel, or their clocks will begin to drift erratically, and at some point in the foreseeable future, the constellation will lose enough satellites that it will be mostly unusable. So if we'll be launching new ones anyway, why not make them better?
I also understand your humanitarian question, however, the support that GPS provides in science and education (even though it was and is a military project in the USA) truly does humankind a great service. Oh, and it lets me find good pizza no matter where I am in the city, which is truly humanitarian

Perhaps I've been in the computer industry for far too long, but how could it possibly cost 1.4bn to essentially add access control and a bigger amplifier to existing tech ? Will it realistically provide 1.4bn back in value, either by gaining efficiency in war planning, or enabling new civilian tech to make our lives easier ?
Because the 1.4bn is used for more than what you trivialize it to be for. The 1.4bn is for the entire contract but the initial goal is to only have 2 satellites launched with the option for 10 more. They will be integrating with the existing EU Galileo system and provides who knows what else in additional features. As one guy in the article said "'You are guaranteed a lot of business for the next 20 years. It may be enough to drive the losing competitor out of this market.'" In addition to the materials,

Turning off GPS doesn't give us any more ability to kill people. Simple keeps the enemy from killing us.
Don't underestimate the potential impact it could have on saving lives. Sure perhaps it's selfish to want to save our own lives, but hey I'm only human. If the enemy uses GPS technology to launch an attack on us we only have ourselves to blame.

A warcrime for a Sovereign Nation to control their property?
Why do you think the EU lofted their own GPS network?
Why do you think the Soviets began lofting GLONASS during the Cold War?
If you don't control it, don't depend on it.
