Description

I have some code I did for fun this summer to program LGB seeker replacement for the BIS one.

It'd be pretty much drop in code, it works with all the default laser designators.

It essentially works like the real life LGB seeker in that it just picks up on the strongest desirable signal and then guides itself to that point. This allows pilots to loft bombs from outside the visible area of the target, or from behind hills. No need to lock on to the laser designator. Just make sure that you have a designator lit in the target area and drop the bomb in the general direction of the target with enough kinetic energy to get it there.

Seeker simulates a 60 degree field of view for target pickup and is ... well pretty darn accurate (see: http://www.youtube.com/watch?v=9Gh8kQtTAbg )

I only post this instead of just adding it because it would effectively change how the GBU-12 is used and that seems like one of the more common ordinances dropped in game.

Sounds good.
Does it work with AI too? As in AI pilots will still drop bombs on laser dots?

Updated by Nou over 4 years ago

Presumably. All this would entail is on some machine (either the pilot or the server) catching the bomb with the fired event handler, replacing the one thats being controlled by the BIS guidance with a new copy in the same vector/velocity and turning on my guidance code.

I also have code that works on taking a grid position, so basically a JDAM, but I need an interface for that for the pilot to enter in the grid or UTM coordinates they want their bomb to fall on.

Nice work, very much needed.

Yeah JDAM would be nice In combination with a vector/dagr it should provide good stand-off CAS

It would be nice to eventually see a system where you could actually enter in the laser code on the Designator and radio it to the pilot. There may be situations where 2 JTACs could be working 2 different targets in the same vicinity. Wouldn't your proposed system interfere with other people lasing targets in the same area?

I know the maps aren't that big, and there isn't usually massive amounts of CAS flying around that would require tons of control, but still I can see it being an issue.

Yea, this is one of the things I been mulling over. I am not sure if its possible to vary the laser objects... I don't know if setVariabling on them works at all... If you could designate what objects the designator spawns you could create a limited number of different objects... Not sure how many codes are available.

Wow nice :-)
Definately for it!
Regarding the piucture: In the real-version, is this also a GBU-12? 500lB or rather a bigger one?

Should be available in the about to be release ACE 1.7 RC1

Updated by mr.g-c over 4 years ago

Wow will try it ASAP.
Will it be documented how to properly use it now, because of "Seeker simulates a 60 degree field of view for target pickup" ?

Updated by Nou over 4 years ago

Yea Jay and I will write up some documentation for it pretty soon. The laser is also impeded by hills, there has to be line of sight to the seeker for lock-on to occur.
