Satellites can operate drones any where in the world. Drones only limitation is battery life.

Can satellites use lasers to charge batteries?

>Can satellites use lasers to charge batteries?
Microwaves not lasers, lasers are too inefficient in conversion both directions and have too much atmospheric attenuation. But space based solar power using microwaves has been an area of active research, so you can start by reading up on that. Taking as given that the costs of stuff in orbit will continue to plummet with Starship and various future competitors, it'll be potentially feasible and economic enough on the space side. The challenge like all things airborne ultimately comes down to whether the weight and size requirements imposed by a receiver are actually worth it, particularly given that plummeting cost of stuff in orbit also works to enabling massive numbers of VLEO sats that can provide perpetual high res surveillance and high bandwidth low latency comms themselves. What role does a drone with unlimited loiter actually fall into, vs the same drone with more carrying capacity that just automatically cycles with others to recharge/refuel back at base?

Looking at that image made me think of something: Long range drones are bigger than fighters and some WW2 medium bombers, require massive amounts of expensive electronics and satellite guidance, ect. They all have the big dome for the dish.

Why couldn't you make manned versions? You could fit 2-3 guys in there easily, for low risk missions a manned version of a reaper or global hawk would work just as well and probably cost a whole lot less. Even for combat missions the loss rate is less than a WW2 bombing mission, if you were willing to accept the losses why not?

Can they? Hypothetically, yes. Practically, no. The technology just isn't there yet.
However, something that IS possible right now is solar powered drones with 100%* uptime, either as flying wings basically made of solar panels, or balloon-blimps that also carry solar cells to keep themselves running indefinitely but obviously aren't going to be moving anywhere quickly. I could see some kind of hybrid fat flying wing that's also filled with hydrogen covered in solar cells being useful- infinite flight time but a bit less of a slave to the winds.
*outside of needing to land for regular maintenance etc
Oh also,
>Pretend you have your battery-charging lasers
>Ok great. How do you power them in the first place?
You would basically need to put a nuclear reactor on your laser satellites just to power the lasers unless the satellites were so massive they have an absurd amount of solar panels, since it's not exactly practical to refuel a satellite every time it needs it's lasers recharged you need a significant power source that also doesn't need refueling/recharging logistics.

If you can relay power through lasers why not just put an xboghueg nuclear reactor on the ground and use the satellites to beam the energy wherever you need it? Efficiency will be ass but since you're not limited by the cost of putting your reactor into orbit you can generate more power than you would ever need.

The B-2 has side-by-side seats and a little of extra room to rest, but in general you'ld not rely on pilots for long missions even if they can "sleep". A drone will be better for longer missions.

The issue is more "how to collect the power" than "how to make big laser".
Also, lasers are far more effective in space or at very high altitudes. Unless you make some kind of Dr. Evil mountaintop nuclear laser facility to beam up to space you will be losing a significant amount of your power just chewing through the atmosphere, let alone cloudy days.

The point was that for many of the missions they do return home, global hawks are not one use items and the AA threat over places like Afghanistan is non existent. I was pondering if one could make cheaper manned versions for low risk missions, i was envisioning a modular cockpit you could swap out of a airframe with the drone 'cockpit' having the really expensive stuff.

>require massive amounts of expensive electronics and satellite guidance
A smartphone has enough computing power to guide a rocket to the moon. Its not "massive" nor expensive. The chips are like $10 on the market. Raspberry pi is like $30 with all the connection ports required for any external hardware control. And arduinos are $3-10 with full wifi/bluetooth/usb connection port powered by sub 1watt of power. All these have enough compute to do trillions of calculations per second. This isn't Vietnam era computing anymore. Further connection to satellite just requires a starlink mini that weighs like 1 kg or <2.5 lbs that can be hooked on top of the drone and provide wifi or ethernet signals. And only consumes ~25-40w of power for max bandwidth. and only costs ~$200 for hardware and $165(?)/m for unlimited bandwidth global access.
For everything else in the plane, the steering on the plane is steer by wire, so its computer controlled already.

Old vehicles designed 20 years ago, made 10 years ago, in used currently.

Mini starlink dish is slightly smaller than 1 ft x 1 ft. We're in the new age. Legacy geostationary sats and their dish are outdated. Legacy aircrafts are outdated. Legacy computer parts are outdated. In the span of 20 years, all the airplanes built 10 years ago, designed 20 years ago have completely out dated computer systems.

yes but it would be retardedly inefficient and expensive. besides any super long range drones work on kerosene and dont 'recharge' you could just have refuelling drones that fly out and refuel your drone so it can run for longer. this is a far more practical solution

>>63965731
>US
I hate to alarm you but nations other than the US have big drones these days, some of which have *alternate* ethical values in regards to human life, image related.

Be it as it may, the simple question was could a big drone be made in a manned version. The reason the thought occurred was because there are several loyal wingman type proposals that involve both manned and unmanned versions. If it is being done for fighters i see no reason why surveillance craft couldn't do the same or even attack craft if you didn't care as much as the US about human life.

Personally i think using huge drones for stuff like Afghanistan, border patrol and other peacetime duties is moronic. Airships would do it better, cheaper and allow us to pursue a alternate technology/industrial base at the same time.

Yeah, big observation drones. I'm not saying that you should make them manned as this conversation has gotten a bit of course. I'm asking why couldn't you use something like a Reaper or Global hawk as a manned system?

I don't know if they would be cheaper but big drones are approaching the size of thing like a Il-28, i am asking if humans would be cheaper than the systems required to run them.

The crew of the B-2 and B-52 can rest, there's enough room for that and the side-by-side seats reduces fatigue too (a retard above thinks the B-2 has a tandem cockpit). Torpedo bomber and escort fighters during WWII were incredibly taxing with missions of ~5 hours, 8-10 hours rarely (for example Zeros, but those were designed to be stable enough to fly hands-off), even if they took 'stimulants'.
The B-58 Hustler and B-47 Stratofortress were terrible for their crew even for missions shorter than 10 hours.
That's why all fighter bombers and bombers with long endurance have side-by-side cockpits and even extra room.

Ok, there's an exception, the F-117 Nighthawk, and that flaw probably was the reason for its retirement, pilot fatigue probably was responsible of the 1999 shootdown and fatal crashes.

No, and even they end up becoming addicts to amphetamines/modafinil to last +10 hours, a normal GH would still be more effective and you need less drones for the same role...
And you can't go too cheap, the russian air force is far less effective than the US air force because they can't into data integration and some classes of sensors, those aren't cheap and a manned aircraft still needs them.

Considering the limited battery capacity of the satellite, and the inefficiencies inherent in any energy transfer system (especially one travelling through most of the atmosphere), you'd probably be better off spending the money you'd need for something like that on just having a larger fleet of drones to be able to replace the one on station when it runs low on fuel.
