A beam rider guidance concept and transmitting assembly including two synchronously rotating discs with beam modulation patterns thereof positioned such that the modulation pattern on one disc passes through the centerline of the projected guidance beam in the elevation direction and the modulation pattern on the other disc passes through the beam in the azimuth direction. The discs are closely adjacent, and have clear reticles or spaces included to allow uninhibited beam passage where necessary. Where other clear reticles or spaces appear in both discs simultaneously, various digital on-off light signals are sent to a receiver in the guided projectile or projectiles, to perform functions of synchronization, calibration, and address codes and bias guidance position codes applicable to a plurality of simultaneously guided missiles or objects directed to individual respective targets. The guidance beam is a pulsed laser, for example, having electronic pulsing control and also pulse timing dependent upon disc position pick-off means. The pulse control may be delayed slightly on predetermined successive revolutions to provide a greater resolution of guidance position control.

Beam rider guidance apparatus for a guided object, comprising a light beam generator for projecting a light beam toward a target and onto said object when the latter is launched at said target, a pair of rotating reticle discs in the path of said beam, each of said discs having a series of reticles thereon in a circle centered at the axis of rotation of said disc, one of said discs being an elevation guidance disc having its reticles passing in a vertical direction through said path of said beam, the second disc being an azimuth guidance disc having its reticles passing in a horizontal direction through said beam path, each of said series of reticles comprising a plurality of clear reticles and a plurality of guidance reticles having a light-blocking portion and a light-passing portion wherein said portions are at different positions in each of said guidance reticles to form an advancing pattern circumferentially of its respective disc as said disc is rotated, and means for connecting and driving said discs in a synchronous manner to project said beam through a guidance reticle on said elevation disc and simultaneously through a clear reticle on said azimuth disc, and at different times in said rotation through a clear reticle on said elevation disc and simultaneously through a guidance reticle on said azimuth disc.
