The group further includes means for protecting, adjusting and for testing of such mechanical sighting devices. This group further includes weapon mounted means for illuminating the sights or the the target.

The present group is a combination of two distinct concepts, a document classified here should have parallel entries in F41G 1/02, F41G 1/06.

Arrangements for maintaining the aiming direction of a weapon mounted on a mobile platform.

Arrangements for testing or checking elevating or traversing control systems for weapons

Though the title of the group refers to elevating or traversing control systems for guns, this group applies to elevating or traversing control systems for weapons in general (e.g. missile/rocket launchers).

Specific details relating to sensing elements determining distance, direction and velocity are classified in the relevant groups of G01S.

Arrangements for the determination of the relative position between a guided missile and a target.

Preparatory measures taken before the launching of the guided missiles.

Beam-riding systems correspond to systems wherein a missile is guided in relation to a reference direction defined by a beam projected from a remotely situated system and received directly by the missile.

F41G 7/34

Systems making use of satellite navigation systems (e.g. GPS, GALILEO, GLONASS) do not, for the time being, have a dedicated group and should be classified in the top group F41G 7/34.
