[Also in Division F3] In a system comprising tracking means obtaining position-data relating to bodies F and Z and wherein the motion of body F is controlled so as to reduce control signals formed by comparing such data, the control unit incorporates delay of the position-data relating to F and/or Z and generates control signals representative of the rate of change of the difference between angular components of F and Z position-data. The system may be such that the Z position-data is supplemented by programmed data such that F may be controlled in anticipation of Z's movements. Body F may be real or be simulated by a sight on a gun barrel. The system may bring about or prevent collision between F and Z. In one embodiment (Figs 2 and 3) F and Z are a guided missile and a target respectively, both are tracked by known radars to yield respective range r, azimuth α and elevation # data rF, αF, #F and rZ, αZ, #Z; the Z data passes through an optional delay unit (S2) and that relating to F through a delay unit (S1 yielding output signals rF*, αF*, #F* (* signifying delay). The quotient rZ/rF* is formed by a divider (RD) in a delay control circuit (SR) which incorporates a temporal differentiator (D1) following the divider and the output of the differentiator controls the delay in unit S1. A command signal circuit (KS) forms quantities #α=αF*#αZ and ##=#F*##Z, these quantities being differentiated temporally before transmission to the guided missile which is caused thereby to collide with the target. For anti-collision, constant magnitudes are added to the signals d(#α)/dt and d(##)/dt before transmission or a pre-set delay (V) may precede delay unit S1 In another embodiment (Fig. 4) body F is an infra-red emitter attached to a gun barrel (whose azimuth and elevation are controlled by the command signals) and tracked by a known device; the delay (V, Fig. 3) then provides for lead synchronism. The emitter is located to allow for the ballistic course of the gun's projectile. The delay units may be of the magnetic drum type (Fig. 5). The delay control circuit (SR of Fig. 3) is described (Fig. 6); division is by variation of the negative feedback by the signal rF* of an amplifier fed with the signal rZ.
