   Laser IRS are so accurate nowadays that it gps isnt needed for such a short trip, as long as you dont care about hitting within 1m.

     @gentoobro @epictittus the problem figuring out where you, the missile is. If you have something like GPS, you don't need to worry so much about drift of measurements since you can refresh.
     
     As an simple example: if it were easy to guide missiles, SpaceX wouldn't have lost a ton of rockets.

     @epictittus @sickburnbro Just use a camera and cached satellite photos. This is roughly how a tomahawk guides itself. There are few practical jamming methods.

     @sickburnbro @epictittus For low-ish flying guided missiles, the missile has an onboard downward pointing camera which it compares to cached aerial photos. It's very effective. I believe the tomahawk used a radar version, but the principle is the same.

     @gentoobro @epictittus right, there are many options that don't need gps, many of them are pretty neat.

     @gentoobro @epictittus but all of them have tradeoffs. ( And we're seeing the tradeoff GPS has - don't use geolocation schemes controlled by people who don't like you )

     @sickburnbro @epictittus High-flying ballistic missiles are another story, but you really shouldn't be using those as weapons anymore anyway. They're much easier to detect, track, and defend against than something skimming the surface.

     Guiding hypersonic glide vehicles is probably a huge pain in the ass. GPS is likely too slow and onboard cameras would be a big blur. My guess is they're some combination of high precision inertial guidance and target illumination where possible. Online sources are rather vague about the details.

     @sickburnbro @epictittus Not only that, but it's relatively easy to jam. All of the current satnav ones are. The US is extremely dependent on GPS and it will come to bite them should they go to war with a country from the 21st century.

     @gentoobro @epictittus my assumption would be that if Russia really wants a fight, they'll just destroy the constellation.

     @sickburnbro @gentoobro @epictittus Maybe S-400 systems, and I believe Iran is on a par with Russia as far as drone tech.

     @epictittus yes, a gyroscope helps provide orientation, which is one important input for guidance

     @gentoobro @epictittus @sickburnbro The other part is do they have the economy to wage war. Decades of sanctions may have made them more self sufficient than the west realizes.

     @AsukaNeko @epictittus @sickburnbro We have really yet to see what sort of air defense Iran really has. They seem to keep much of their tech under wraps until the last minute.

     Laser INS still suffer from precession, just not as much as the old ones.
     
     And extraneous g-forces can induce errors, so no yanking and banking on the way in.

     @Vulpes_Quartus @epictittus @gentoobro the problem is that contractors don't invest because they have responded to incentives, and those are that the government will drop a contractor in a heartbeat.

     @gentoobro @sickburnbro I saw a vid of a drone factory in russia, they are ramping up to mass production, Ill try to find it
     
     Edit: Found vid
     
     Its not difficult to make, they just never did it...

     @gentoobro @sickburnbro Iran is more secretive, but theyre not at war right now. Comparatively, theyre both genuinely better off than a lot of western countries conventionally, maybe all.

     @epictittus @sickburnbro Iran is the only country that appears to be taking drones seriously. China has a few toys in development. Russia has Lancets, but they're still on the pricey side and not producing nearly enough of them. The US has quadrillion dollar pilotless F35's that might be combat ready in 10 years, assuming Boeing doesn't decide to milk more cash out of the project.

     Iran, on the other hand, is the biggest military drone supplier with a large variety of models at very low prices. They also have built a dedicated drone carrier and have two more in drydock. A converted cargo ship isn't the best platform (submarines?) but it's not much worse than the US aircraft carriers.

     @gentoobro @sickburnbro Iran is ahead in production, not tech. Russia probably has better tech but its sitting in a drawer or on a piece of paper in a binder. Iran has produced a shitload of materiel and snuck it away into underground warehouses, thats why Russia turned to them for drones.

     @epictittus @sickburnbro I suspect that Iran is not tipping their cards whereas Russia is talking bigger than they are, in net, all in all.

     @sickburnbro @epictittus By my estimation, it's the other way around. Iran is likely technologically ahead of Russia in net right now. Clearly they lag in space launch and nuclear, but those aren't particularly important in modern warfare so long as you can cause problems for satnav weapons. Which they have already demonstrated.
