Abstract : The system for aiming of a missile strapdown Inertial Measurement Unit for cases 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.
