Abstract: Method and apparatus for transferring alignment (attitude) from a land navigation system (LNS) mounted on a carrier vehicle to another structure such as a missile launcher or a radar station. The invention also embodies a scheme for verifying the accuracy of the transfer concept. The essential feature is a mechanical interface between the protable element of the LNS and the housing of the receiving structure. The interface is accomplished through two rods attached to the LNS portable element and two mating V-groove parts attached to the receiving element housing. The scheme is simple, rugged and inexpensive and is different from other methods in that alignment is transferred mechanically via the rod/V-groove mechanization.

Abstract: Apparatus for transferring azimuth alignment with modest accuracy to the dance systems of individual missiles in a pod configured for vertical launch. The apparatus includes a mechanical interface between two rods (attached to the missile and oriented to the missile's guidance system) and two v-groove elements (attached to the launch tube and oriented to a northfinder mounted on the pod).

Abstract: The system for aiming of a missile strapdown Inertial Measurement Unit for ases in which the IMU does not possess the capability of self-aiming involves no mechanical link between northfinder and IMU which would require uncoupling prior to launch to avoid expending the northfinder. The technique maintains an automatic, hands-off capability by use of a laser link for azimuth transfer rather than a manual, optical link. The northfinder and laser system are launcher mounted and are therefore not expended with the missile.

Abstract: Apparatus for fast, accurate aiming of a missile from a launch vehicle. The pparatus permits fast accurate aiming of a missile inertial measurement unit for cases in which the inertial measurement unit does not possess required performance capability for self-aiming. The apparatus involves no optical link and is not expended with the missile.

Abstract: A radial arm tracker with a constant drive ratio for use in monitoring the osition of a guidance platform during the firing azimuth alignment phase. One end of the radial arm is mounted to the rotor of an encoder and a telescope is pivotally mounted at the free end of the radial arm through a constant ratio drive system to a stator of an encoder. The stator of the encoder is coupled to a north seeking device. The missile firing azimuth is referenced to the output of the north seeking device through the radial arm tracker.

Abstract: An electromechanical lag angle detector device in which the lag angle of a iber that is being wound on a bobbin is sensed by an electromechanical lag angle detector which causes an output signal to be produced which is proportional to the variation from the preset lag angle to provide a signal to a computer for causing an adjustment in translation of the bobbin in accordance with the sensed lag angle of the fiber.

Abstract: A process for terminating the winding of one fiber layer being wound on a bbin in one direction and beginning the winding of another layer in the opposite direction wherein the bobbin is alternately rotated and traversed in small increments to obtain a transition from one layer to another which is free of gaps between adjacent turns in a layer and which does not slough off the bobbin.
