missing info TGP locks onto underground position

[dutchili]

In NTTR my entire flight was unable to lock targets with the TGP. When aiming at the base of things like a SA-3 TR, the tgp seemed to drift when flying around the target.

A low level ingress loft would show nothing on the tgp when clearing terrain cover as the tgp was pointing somewhere else. 

Also, the HUD LOS would indicate range to terrain instead of the target, even when selecting a marketing and not locking with tgp. (Not a point track, just CZ)

Expected behavior: with LOS and point track, TGP maintains lock on target through contrast detection

Which aircraft were you flying?

Do you have a DCS track showing this issue?

F-16.

No track available. But easily replicated.

I found a post by @lordvader that this has to do with GPS and INS inaccuracy, but point track is contrast based isn't it?
