Abstract
A marker that can be used to increase the precision and efficiency of the guidance of homing heads towards a target. In order to mark targets on land, this marker has: an ovoid casing provided with a firing fuse, and a magnet and a coil for detecting flux variations during an impact on a magnetic surface. Inside the casing there are: a battery, an electronic control and transmission circuit, and a cylinder of thrustors connected to one another by pyrotechnical delaying mechanisms. The cylinder opens out on to a single nozzle which is inclined with respect to the axis of the casing. After impact on the ground, the electronic circuit controls the firing of the first thrustor. The other thrustors cause leaps until the marker gets fixed to a magnetic surface, through the magnet. After detection of a flux variation, the electronic circuit actuates the firing of the fuse, to eject the casing and the cylinder of thrustors, and triggers a microwave or infra-red transmitter, depending on the homing head to be attracted.
