Second Galileo Test Satellite Now in Orbit

Posted by ScuttleMonkey on Mon Apr 28, 2008 04:38 PM
from the still-plugging-away dept.
Simon (S2) writes to mention that Europe's second Galileo navigation satellite reached orbit this past weekend. Galileo is promising to offer several technological advances in comparison to the US-based GPS system but no longer promises to be a guaranteed service. "The Galileo programme now seems certain to go ahead, after a prolonged and painful shift from partly-private financing of the construction to public funds taken from unspent EU farm subsidies. This money would normally have been returned to donor nations, with the UK, Germany and the Netherlands as the biggest three. London MPs have expressed doubt as to whether the UK will receive value for the money it will pay, but have acknowledged that the British government doesn't actually have any choice about Galileo under EU funding rules."

[+] Lockheed Martin Awarded GPS III 154 comments
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.'"

        Give us some credit. We most certainly do recognize locations outside our backyard. "Overthere" is a well recognized location. But my memory fails me trying to remember some of the other well known places.

      Even better, they can tell in which of 4 possible locations on the earth you are!

      You're either in sight of satellite A, B, both, or neither.

      That really narrows it down!

      Of course for the case of both, you are probably already in orbit, so that really doesn't count as "on earth".

      Lets stick with three then. We can claim a 50% improvement on the number of locations you could be in over the previous 2(can see satellite/can't see satellite).

      Whew, and I'm spent. Good job.

      You are misinformed. The galileo satellites are the first of a new breed of reverse GPS. Using your known location on earth, the satellite(s) triangulate THEIR location and consult an on-board map of turn-by-turn directions so that they can find nearby gas stations, restaurants, and space stations. It's the first step in establishing a network of McDonalds in orbit, a necessity before space colonization can begin.

    Why London's MPs? What's so special about them?

    There are 645 MPs in the UK, of which only 74 are in London. Quite why they should be supposed to have some special insight into Galileo or farming subsidies is beyond me.

      On the other hand, I wouldn't tell them. Just keep quiet and maybe they won't interfere with your life too much.

    Instead of starting a new system from scratch, they could have made it an extension to GPS. Imagine better altitude detection, less ionosphere interference. Good thing those farm subsidies went to good use.

      Galileo is intended to provide more precise measurements to all users than available through GPS or GLONASS, better positioning services at high latitudes and an independent positioning system upon which European nations can rely even in times of war or political disagreement.

      The last part is less of an issue now...

      A reason given for Galileo as an independent system was that, though GPS is now widely used worldwide for civilian applications, it is a military system which as recently as 2000 had Selective Availability (SA) that could be enabled in particular areas of coverage during times of war, and therefore Galileo's proponents argue that civil infrastructure, including aeroplane navigation and landing, should not rely solely upon GPS. On May 1, 2000, the President of the United States signed an order disabling SA, and in late 2001, the entity managing GPS confirmed that the intent is to never re-enable selective availability.[14]. Though Selective Availability still exists, on September 19 2007, the US Department of Defense announced that they would not procure any more satellites capable of implementing Selective Availability.[15] This means the next wave of Block IIF satellites launching in 2009 will no longer support SA. As older satellites are deorbited and replaced, as part of the GPS Modernization program, SA will cease to exist. The modernization program also contains standardized features that allow GPS III and Galileo systems to inter-operate, allowing a new receiver to utilize both systems to improve accuracy.

        By that same token, I wonder if the EU Galileo satellite network will be as generously shared with the general public as the US GPS system is with the world.

        Now that I've got the nationalist pride bullshit out of the way, any system that can provide better and more accurate coverage is certainly welcome in my book. They could call the new satellite system "The Flying Turds" and I'd be ok if it let me get better than accurate to 12 feet. :)

            Currently the GPS system is being upgraded to offer increased accuracy and additional features. This is known as GPS III [wikipedia.org] and is scheduled to be fully operational by 2011 to 2013 (or roughly the same time as Galileo is supposed to be). According to some sources [globalsecurity.org], it will enable accuracies down to 1m un-augmented.

        Yes because GPS is owned and controlled by the most dangerous army in the world !

        Armies are like guns. They are not dangerous, until you (aim and) pull the trigger.

        That being said, as a European, I'm not comfortable with a critical infrastructure like GPS in the hands of the US. The current administration has shown that it is incapable of handling the power and responsibilities that come with being a superpower. Former US presidents warned for the influence of the Military-Industrial complex, but that lesson seems to have been forgotten, resulting in "Bringing peace and democracy to the Middle East".

        The original post was a mess. But subsidies in richer nations do lead to poverty and starvation elsewhere. By subsidizing grain production, prices have been artificially low for many years. This means poor farmers can't compete and stop producing as much. The added imports is a drain to those countries' economies. If there is any disruption to the supply of grain, either through famine, currency problems, or prices jumping on the imported grain, the local population suffers.

        Had grain prices gone up slowly, it would have been a good thing. It was the sudden shift to ethanol plus crop problems in several world breadbaskets that pushed up prices. If sufficient grain had been grown locally, it wouldn't be as much a problem (maybe even a plus if they could export and get hard currency for it).

      And it while we're at it, lets give the great city of Bristol the power to take back the money for projects *they* don't think are a good idea.

      Generally when having a overall budget you do not give the constituent parts the ability to pick and choose. The Galileo project is part of the overall EU budget, therefore the UK doesn't get to second guess the distribution. (never mind that the UK pays far to little into the budget anyway).
