Osa - wrong tracking method.

[Koty]

Hello,

the tracking method used is wrong. The method being used in DCS is proportional navigation, however, the correct method should be three-point.

Three-point is main guidance method, there are secondary methods (for vertical guidance only) for low-flying targets and helicopters, although it probably won't be possible to include multiple tracking methods.

Three point method, in short, means system is trying to align 3 points into a single line, that being put the point of the missile on a line formed by launchhing vehicle and the target. This then makes the system a fully-automated command line-of-sight system. Semi-automatic command line-of-sight method is used when target is tracked manually via a high-magnification camera system instead of automatic radar tracking. In case of interest I can enclose the pages explaining the main guidance method.

Shouldn't this also affect other systems?

There might be other systems with this problem, but no, this is very individual. But it might be worth having a look at other systems, like roland. I'll have to have a look at how the S-75 missiles track, but for that we'd need a proper implementation of full command guidance.

I hope the devs see this and are able to adjust the behavior of the SA-8 accordingly. Should be a lot more dangerous

This is a good point, 3 point tracking alone will prevent people from just driving the missile into the ground. Would be even better with the other modes available, however the manual was not specific on how they function, so at best we can make assumptions that Gorka is some sort of lofted guidance and H is for constant altitude (H missile = H target). But this is just an educated guess.

I've realised this could probably be moved to https://forum.dcs.world/forum/423-ai-bugs-non-combined-arms/ or somewhere more appropriate.

Well spotted, I hope it gets changed.
