Rapid and Robust Transfer Alignment

The design of a rapid and robust transfer alignment system for advanced kinetic energy missiles (ADKEMs) is presented in this paper. Owing to the high acceleration level and reduced engagement time of the ADKEM, the transfer alignment which aligns the salve (missile) inertial measurement unit (IMU) with the master (ground launch vehicle) IMU must be accomplished in a short time with high accuracy. The scope of transfer alignment system design presented in this paper encompasses the assessment of inertial guidance accuracy, transfer alignment formulation, maneuver scenario design, and sensitivity analysis.
