They have IOG which has a certain amount of inaccuracy/drift. Its meant for getting the missile into the general area before then either using the MMW seeker to find the appropriate target or the laser. The latter being what we have.
The Brimstone 3 appears to get upgrades to its Inertial navigation, which could translate into essentially 0 drift IOG in game, that would result in something roughly akin to GPS guidance, but that isnt the version we currently have modeled.
Brimstone doesnr have GPS, its a rough IOG.
Strictly speaken as it works right now it shloundt be able to work. We are simulating the mmw /Man in the Loop LOAL a bit with it , but cant work on oure GPS
