Narrowing guidance cone?
Don’t standard laser beam riding missiles have a guidance cone that expands over distance? (STARstreak is the only missile immune to this issue last I heard).
Or are you talking about the Hellfire with that?
Okay, i found the update notes and see what you mean. They had added a timer to replicate the cone shrinking over time. But not the actual guidance system.

No it shrinking over distance. The 114 just runns towards a laser pointer like a cat.

Lasers dispers and lose intensity over distance sad limitation of the inverse square law.
Laser points don’t get smaller over distance, they get larger, dispersing the energy over a larger area. That’s why a burning laser can put holes in a tin can at 30 cm distance but barely destroy a thin layer of paint at 30m.
The hellfire has a system to determine the area within the laser dot is the center, giving it unparalleled accuracy for a SALH missile. That’s why the AGM-114R-9X can make do with a ~1.5 meter diameter kinetic warhead. Much more accurate than a cat chasing a laser dot.
I think that’s what @Steelbeast meant but I could be wrong
I’m pretty sure we do have it in game but for only tanks. I’ve seen it on the T-series tanks with their ATGMS, the TOW systems (different guidance type by have the same effect) and some others. But it doesn’t look it was applied to helicopters.
Though I’m curious on how accurate the Apache fire control system is
I was talking about beam rider guidance cone.
Except that timer does not capture the fact that missile can fly out of the cone, in some situations, like tracking targets with high angular velocity etc.

Following the discussion he is giving an example of 2 different guidance types. Saying the vhikers cone will shrink over time to improve accuracy at distance cause beam riding. But a hellfire tracks the laser point which is more like a cat not beam riding.
U sure? I had RBS 70 lose the beam a few times in my ASRAD-R.
Oh, I get it now. Now when thinking about this for a bit longer. This is how I see it.
As Vikhrs get farther away, the beam at which the fire control system (laser) is set shrinks to improve accuracy. One downside of this, is that as the cone shrinks the missile isn’t allowed to move as much. If the missile moves too much, it might get out of the cone and the missile will not follow the beam.
A way to counteract this is if the missiles goes out of the beam, the beam will temporarily widen until it recaptures the missile, and the beam will shrink gradually again.
I think this is how it works but I could be wrong. Thoughts? @Steelbeast , @BeautifulTai_wan
Yeah except I don’t think the beam will increase in size to require the beam. Gaijin did a decent job in explaining here.
They quietly reversed this about a month ago, Vikhrs can be used to shoot down VT1s again, whether the SAM has the heli locked via Radar or IRST.

Weather they did or not is something on Gaijins decision. I was using the link to provide more information to honda about beam riding.

I see, thank you for the article. Though I don’t understand why some systems that use beam riding don’t work the same way as the Ka50/52.
For example the ADATS missile is very sparatic. Does the cone get narrow over time for the ADATS? It feels like the cone is static and the missile just bounces around within that cone?
Edit: Maybe if it’s too narrow, sudden maneuvers from the plane will throw the missile off?

Quite possibly but as others have shown in this topic Gaijin hasn’t modeled true beam riding they have something else supposed to act like beam riding but isn’t. From what Gaijin has hinted at in the past their games limitations prevent true beam riding modeling.
Yeah, hopefully they do model beam riding correctly because as of right now, there’s no reason to pick laser over beam riding. Beam riding is way too reliable.

I’m talking about the two different missile. The vakhrs that use a rear facing sensor that has a cone IR light that shrinks and the AGM 114 front facing sensor that looks for the reflection from a laser pointer like how a cat follows a laser dot.
That’s why they use a 10 kilowatt laser.

Yes, I think all missiles from the code perspective are modeled like the SALCOS missiles, on top of that all the rolling airframe missiles (RAM) like Vikhrh or manpads ale modeled lake normal missiles.
Actually ADATS irl has dual SALCOS/beam rider control. SALCOS is for the post launch control to ensure that missile will fly into guidance beam. That is not modeled either and it would fix the problem with ADATS launcher elevation.
Another missing thing is that systems like ADATS, Startsreak (evidence presented in why is Stormer so bad topic) etc can lead the missile, so the FLIR and guidance beam are not linked.
I don’t think that GOES has something like that, since it was not intended for the AA role.
