Lockheed Martin Awarded GPS III

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.'"

What is up with Boeing lately?

Seriously - lost the in air refueler contract to Airbus (or NVS or whoever)- lost this contract to Lockhead - What is the deal?

a ten-fold increase in signal power ... a new civil signal compatible with the European Union's Galileo system

I think that translates to "ability to override the European Union's Galileo".

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.

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?

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.

Incorrect. From http://www.fas.org/man/dod-101/sys/smart/jdam.htm
"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.

Does interoperate with Galileo also mean JAM?

[viking80]

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.
