A beam rider guidance system is presented which uses a rotating laser light pattern to enable a weapon-borne laser receiver to derive its position relative to the beam axis. The guidance beam consists of changing light patterns detected and decoded by the receiver as a guidance code, which defines the unique weapon position in the beam. The code is composed of four distinguishable patterns of light bars which can be detected and decoded into electrical pulses by the laser receiver located anywhere within the confines by the guidance beam.

A projectile guidance system comprising: a source of continuous coherent light for generating a light bundle travelling along an axis; a disk having a preselected pattern of radial light bars thereon arranged in sets of differing angular width for modulating a light bundle from the source which is projected through the disk; means for moving the disk so that the light bundle traverses along a circular path through the sets of radial light bars relative to the disk, whereby a modulated beam is projected into space from the disk and along said axis; and optical receiving means mounted on a projectile for detecting the modulated beam and determining the projectile\s position relative to the axis of the projected beam.
