Robot Plane Makes Unaided U.S.-Australia Crossing
PenguinRadio writes: "Yahoo Australia is reporting an unmanned U.S. aircraft recently flew from the US to Australia, smashing an endurance record for remotely controlled aircraft.

I suppose I'm a pedant, but "endurance" means time aloft, not distance flown. This plane set a record for distance flown by a robotic plane, not the record for time aloft.
I can't see how less than 24 hours en route qualifies for an endurance record, since a small (10 foot wingspan) robotic propeller-driven plane called an "Aerosonde" crossed the atlantic in August 1998, taking about 26 hours 45 minutes. In fact, I seem to remember that /. carried that story, though
I don't find it in a quick search.
I did find a few other stories from that time, though, at ABC and EXN, and you can always visit Aerosonde Robotic Aircraft if you are interested.
I think, but do not know, that there have been robotic flights longer in duration than that, but I don't have time to look for them now. :-)

Honestly, just flying unrefueled is fairly trivial, and as for guidance, does the term "cruise missile" ring a bell?
I wonder how it's programmed to respond to other aircraft in the same airspace?

With a name like Tandem Thrust, you'd think this was part of a raunchy 80's metal band, not a military operation. What's the follow-on to this, Turgid Probe?

What's interesting is that Global Hawk represents the fulfillment of the original goal of the old Teledyne Ryan Compass Cope project from the 1960's: a very high-altitude unmanned reconnaissance drone.
However, with access to GPS signals plus a real-time satellite link, Global Hawk can precisely controlled to fly over areas of military interest, unlike the Compass Cope drone, which was flown on a pre-programmed route.

Actually, Global Hawk has a built-in satellite communications antenna, which does allow for real-time monitoring and adjustment of flight route.
This makes it much more flexible than the old Teledyne Ryan Compass Cope RPV from the 1960's, which was designed for a fairly similar mission to Global Hawk but flew on a pre-programmed profile. Also, the nice thing about Global Hawk is that you don't need a dedicated launch aircraft like what the Compass Cope RPV's required, which saves a lot on operational costs.
Raymond in Mountain View, CA
However, no public source has published what is the radar cross section (RCS) of Global Hawk.
If Global Hawk's shape has been tuned for low RCS with a combination of designing the shape to be naturally low in RCS and the plane's skin uses radar-absorbent materials, then even that new Chinese SAM will have great difficulty trying to shoot it down, especially when you fly it at over 65,000 feet altitude.

Fascinating read.. correct link is here too btw (one above had a space in it, that I didn't notice immediately).
It certainly is a reminder of the holes in the world's defense systems. Once you think you've handled a particular threat, another one you never even thought of comes to be your biggest problem.

Yeah, but it doesn't have to not hit anything, does it?
I write a blog now, you should be afraid.

Also, the instrument package being used has been developed at DSTO.
Edinburgh is also home to RAAF's squadron of P3-C Orions, who do a significant proportion of the current coastal surveillance, and may have some knowledge of Australia's requirements for a surveillance platform.

Remote controlled planes have already existed for a long time (called drones), but have the disadvantage of not being radio-silent (have to permantently transmit back instruments reading, camera view, etc) to the base station, which makes them unfortunately easy to detect...

smashing an endurance record for remotely controlled aircraft
I guess this does say aircraft, but I would think that Voyager (or V'ger) would have to hold the endurance record for a remotely controlled anything.

Check out Jef Raskin's website for what he describes as the 'Piper Cub Offense', arguing that GPS-guided drones make missile defense systems obsolete, indeed nonsensical. http://www.jefraskin.com/forjef/jefweb-compiled/un published/piper_cub_offense.html

Chances are that the raw data are NOT being sent anywhere in real time. This is mostly conjecture, but I have some experience with a related weapons system. Some data may get processed and sent out over a tactical or theater datalink, but most of it is analyzed right on the platform. So the mission crew is analyzing the sensor data and providing that digested information to the theater commanders. This includes voice comm intercepts, radar analysis, etc. So the guys on the EP-3 can tell the commander "we have x many aircraft of y type at location z, and we just heard the flight leader say 'foo', so we know what their intentions are."
Keep in mind that the variety of sensors on an EP-3 probably greatly exceeds that on the Global Hawk. The EP-3 has all manner of RADAR and radio intercept gear. Trying to push all of that data off the aircraft in realtime would likely overwhelm the available satellite bandwidth - your average satellite channel has less throughput than a modem, remember.
Long term the goal is to replace a lot of the surveillance/airborne C2 assets (E-3, EP-3, RC-135, etc) with UAVs, but the bandwidth availability is going to have to improve before that becomes possible.

Here I am holding my new x-10 palm remote, and for some reasons, I just feel inadequite. Maybe it's because I don't even have batteries.
This GlobalHawk gadget reminds me of the opening scences of Teminator 2. I was shocked to discover SKYNET is also the name of the British military satellite system since 1967. All we need now is Vernor Vinge's singularity.
As I understand it, it's immediately going back with special US cargo. The $1M winner of course takes their own private jet.
Since Vietnam, it seems that the primary political barrier blocking the military from entering the war of it's choice is the threat of loss of lives.
It's my (unproven) theory that with each military invention that allows the military to strike without reduced risk of loss of life, there is a proportional increase in the willingness to go to war. "Go to war? Why not? All we have to do is hit this button here and an army of robot tanks and planes will raze country foo to the ground. Unless someone trips on carpet and bangs thier head on the sharp metal corner of the control panel, thus dying from a serious head injury, the risk of loss of life is zero." Doesn't that sound like something Congress would be more willing to do than, "We can have a hundred thousand men on thier shores in less than 24 hours. Our analysists guess that the foo counter-strike will cause about a 10% level of casulties for our side, somewhere around ten thousand casulties. Shall we attack?"
Maybe the state's highest function is to grind out insoluble problems. (Zelazny, Hall of Mirrors)

I think the joke was that the Australia spelling is "apologised". I know, it's not very funny.

This shows that the 23 hour flight wasn't the longest. The Global Hawk has flown at least one other longer - 31.5 hours.

I'm shocked this wasnt mentioned earlier in the thread. Clancy's books tend to become reality a year or so after they come out.

but you don't have marauding laser-packing cylon warriors to fend off in the earth's atmosphere either. i think that deep-space specific threat balances out terrestrial contingencies rather nicely.
It's a cool achievement and all...it just seems a little low-key compared to the other interplanetary adventures that remote-piloted machines have these days.
drop bombs to kill friendly troops (without consequence)?
sink the occassional fishing vessel (without consequence)?
piss off Chinese fighter pilots (with the consequence of a slight delay in travel plans)?
guide foreign military powers in their endeavors to shoot down those obnoxious missionary planes (no admission = no consequence)?
Maybe our galoots in green should spend more time working with their human capital than with these nifty machines. Or maybe these robo-planes will be just as good at mistaken-maiming once they've gotten Uncle Sam's healthy dose of "kill 'em all and let the tradewinds sort 'em out" training.
Eloi are stupid, throw morlocks at them!
Does anyone know why the USAF would fly it to RAAF Edinburgh in Adelaide, rather than RAAF Townsville or RAAF Williamtowm? Since it's being deployed in Queensland, it would make more sense flying it closer to where it's going to be used...
"Australia... The land up over, depending on your frame of reference."
...until a civilian starts piloting it...
Japanese glider pilots will shiver in fear.
I believe the reference was the U.S. incident with China. I doubt that with the spelling problems on /., we'd worry about the differences between U.S. and Contential spelling.
To Copy from One is Plagiarism; To Copy from Many is Research.
Even regular civilian planes don't need that much in-flight operation on transatlantic routes. Is it a coincidence that this record was published right after the spy plane incident in China? Might the U.S. be showing off to the Chinese, essentially saying: See, you won't have any hostages next time?
Oddly enough, the robotic pilot demanded 3 quarts of alcohol for... "fuel" before it would make the flight.

"// this is the most hacked, evil, bastardized thing I've ever seen. kjb"
Several posters think this has something to do with the recent spy plane incident, but what I wonder is: Why do they need 23 (22?) people on that plane, including Chinese-speaking Analysts, when all the data collected are send back to base in real time anyway. Just what exactly are they doing?
The news on this several years old robotic plane could be a "I told you so" from the more pro-machine group within Air Force/CIA/Whatever to the more old school people.

Codeala - Just another mindless drone
Pretty impressive at first glance,
but when you consider what it costs
and the gazillions of dollars the USAF have thrown at it's development,
(and the fact that it's wingspan is around that of a 737), it starts looking
somewhat less impressive.
For some contrast, check out These guys
An idea thrown around is to arm unmanned planes with long wings, solar panels, and have them fly across to upper atmosphere for months at a time, acting more like a satelite than a plane...
As the plane flies at almost 20 km, it allows monitoring countries with less developed anti-aircraft systems. As the Air Force lets the world know they have this, they propably have already something better under development.
Nice to notice that Yahoo has more details on this than the Air Force site.
Ehh, bleah. I bow to your superior brainpan and vow to never eat turnips again.
Or at least stop going from memory.

Thank you Goat Police.
I wonder if Austrailia is going to refuse to give the plane back until we apologize for landing it in there country?
... that the US will supplement its ICBMs with inter-continental cruise missiles? These would have the advantage of flying in under the radar, so to speak...
Both robots were tethered. They certainly weren't left to operate on their own for months without repair.

What I wonder is why space-robot designers don't practice by sending autonomous probes to mountain tops, into deserts, to the bottom of the sea, etc.
The specifics are all different, but the principle is the same: this thing has to work on its own, outside the lab, for long periods of time with nobody to replace the battery or change the oil. You could easily build 50 earth-exploring robots for every space-explorer.
So much experience to be gained... it just seems a waste to send up these amateurish space probes with millions worth of rocket and fuel.
