A method for improving an accuracy of a radio based navigation system by correcting the position given by the radio based navigation system with a correction vector derived from localization data stored in a map database. Position coordinates of the radio based navigation system are measured. A set of 3D map data is selected based upon the measured position coordinates of the radio based navigation system position coordinates. The actual position is determined from the selected 3D map data. The actual position data coordinates are retrieved from the 3D map data based upon the determined actual position. The correction vector is calculated from position difference between measured radio based navigation system position coordinates and retrieved actual position coordinates. The position given by the radio based navigation system is corrected with the correction vector.

Method and device for using warheads released from a launching vehicle

The disclosure relates to a submunition disposed to be separated from an aeronautical body, for example a shell carrier canister or the like above a target area, the submunition essentially including a warhead (5), a target detector (6) and a device which imparts rotation to the submunition for scanning the target area in a helical pattern (4) during the fall of the submunition towards the target area. The target detector (6) is pivotally disposed on a carrying shaft (12a) parallel to the line of symmetry (5a) of the warhead in order to permit outward activation of the target detector (6) from a collapsed position where the optical axis of the target detector coincides with the line of symmetry (5a) of the warhead to an activated position where the optical axis of the target detector is parallel with the line of symmetry (5a) of the warhead, so as to permit free scanning vision for the target detector (6) beyond the warhead (5).

Submunitions

A device for reducing the rotational speed of an ammunition unit, for instance a submunition unit, and at the same time imparting to the ammunition unit a lateral speed includes a body arranged to be swung out from the ammunition unit and be released in a specific outswung position. The body preferably consists of a band which is wrapped about the outer peripheral surface of the ammunition unit. One end of the band is fixed to the ammunition unit in such a way that the band is released in a specific outswung position.
