First Successful Unmanned Drone Landing On an Aircraft Carrier

redletterdave writes "Salty Dog 502 flew from the Patuxent River Naval Station in Maryland to the USS George H.W. Bush operating off the Virginian coast, but unlike other drones, Salty Dog was piloted entirely by computer without a human operator. The unmanned operation is considered one of the most difficult operations due to navigating the air and a moving ship, and many have said it's a major milestone in the development of drone warfare. Navy Secretary Ray Mabus described the event as witnessing the future and compared it to the first manned aircraft landed on a carrier in 1911."

      I always love when some random internet wanker posting from his mom's basement posits that a man that:
      a) flew fighter jets for the National Guard (deprecate it all you like, make smarmy comments about his attendance, whatever - nobody doubts that he flew and qualified in fighter jets, which was neither easy nor particularly safe)
      b) Graduated Yale, and earned an MBA from Harvard (it's particularly noteworthy that he's the only president ever with an MBA...if he was a Democrat, that would be widely known)
      c) won an election as Governor of TX over a popular opponent (Ann Richards)
      d) won election to the Presidency of the United States. Won RE-ELECTION (by an even larger margin). ...is an idiot.

      This man has actually accomplished a great deal in his life. Maybe he IS an idiot, but doesn't that make his accomplishments all that more impressive. Particularly compared to you - what have you done? (I mean, aside from generating snarky comments nearly-anonymously on an internet message board? I mean, of course that's pretty impressive alone...)

      Of course, there's practically a Leftist industry of shat-smearing on Republicans (as opposed to Democrats that make 'journalists' legs tingle), so you can't really be blamed. The script has always been "Democrats brilliant, Republicans stoopid" so, if you cheerfully swallow when someone tells you to, that's the impression you're going to have.

      But the sort of self-aggrandizing narcissist fantasyland you exist in to deprecate this man's accomplishments must be...impressive.

      As a internet wanker posting from my own basement I'd say this,

      a) He never flew off of carriers, and joined the National Guard to avoid actual combat service. There is also every indication that he went AWOL during his service to avoid drug testing.
      b) As the son of the family he was in (at that time in American history), getting into those places is not that big of accomplishment.
      c) He beat Ann Richards who was only the Governor of Texas for one term because her opponent completely screwed up his election. Bush was also riding the wave of change in the state that led to the craziness of Tom Delay and the current absurdities going on in our lege.
      d) He didn't win the popular vote in his first election, and won his second election (barely) exploiting terrorism and gay marriage fears.

      And yes I am Democrat, and yes I think W was a terrible president who thoroughly screwed up this country. I do not however think all Republicans are "stoopid". I do think the current crop of leaders such as Boehner and Cantor are not statesman or leaders like Bush Sr, James Baker, or going further back Eisenhower. But the Republican party has been hijacked by extremists, and GWB left our country in economic and foreign policy disasters. So yeah, I think he's an idiot.

      The taunting isn't because he is an idiot. It's because he acted like an idiot, deliberately. He created his 'cowboy' persona, and showed a love of soundbites and a very informal manner of speech. Like all successful politicians, he was also something of an actor. He saw that there was a strong anti-intellectual element in the electorate, and deliberately appealed to them by looking far less intelligent than he really was.

      That is, in my view, far worse than just being unintelligent. He deliberately turned education into something seen as a negative, and gave the impression that someone experienced in pracitcal cattle-wrangling would be more qualified to lead the country than a Harvard MBA... even though he had one himself.

  5. guiding system by Dorianny · · Score: 5, Interesting

    The real question in my opinion is what kind of guiding system do the drones use. Flying by radar guidance is something that we have been doing for a long time, surface to air or air to air missiles use it to lock on a stay on target, unfortunately flying with active radar turned on you are putting a bullseye on yourself that makes it trivial for a enemy with any kind of air defenses to easily track it and shoot it down. Flying with visual guidance is considerably harder (by visual guidance I don't mean simply terrain contour matching to figure out its current location like the tomahawk). Most don't appreciate just how fast the human brain is in quickly figuring out and processing relevant information in the insane amount of visual data that enters our retinas every instant. Computers are nowhere near as good yet.

      Furthermore, a carrier deck has markings and lights at precisely known locations. Just by tracking any three of these points, plus the GAIL (glide angle indicator light), the vision system should have enough information to nail the landing. This landing is a notable achievement, but I don't think the vision system was the hard part.

      I'm not familiar with the X-47 specifically, but nowadays, if you have a solid GPS solution with RTK (Real-time Kinematics) you can get your altitude within centimeters and even velocity vectors, which are necessary for automated landings. In other systems we've used other radar-based landing systems like Sierra Nevada Corporation's UCARS/TALS. These systems track the AV from the ground/deck with a radar beacon that is only active during recovery operations. In systems I've worked with they actually send control commands to the aircraft, but it could also be used to relay displacement from Touchdown Point to the bird and let it fly the approach itself. A deck-based system could also be fitted with inertial sensors to compensate for pitch/heave and give the bird good positions/rates for its approach.

      It would not surprise me if they were using redundant systems to get these first tests. It would also not surprise me if they have already landed successfully in the simulators with all sorts of deck dynamics to tighten up the algorithms.

  9. 1.4 Billion and off to retirement by foniksonik · · Score: 3, Informative

    The Salty Dog is one of two X-47B aircraft built by Northrop Grumman to experiment with incorporating drones onto aircraft carriers. It has a 2,000-mile range and can carry two guided bombs, though it is primarly designed for around-the-clock surveillance. The Salty Dog cost $1.4 billion.

    The drones probably won’t see any combat. After a minimum of three landings on a carrier in the next week, they will be retired to flight museums in Florida and Maryland.

    Instead, the Navy’s UCLASS program will design and build drones for aircraft carriers over the next three to six years. These drones will be used for both reconnaissance and strike missions. According to Reuters, they could be valuable as a counter to missiles in China and Iran designed to limit the range of the U.S. Navy.

    They could have proven out the guidance systems with less expensive hardware. I'm sure some portion of those Billions was directly related to the effort but a significant amount was also dumped into the plane itself as labor and not recoverable.
