摘要

Modern ground based medium range air defence systems demand a highly accurate navigation during the complete missile flight. Especially if GPS aiding of the inertial navigation is not available, for example because of a jamming or spoofing scenario, the accuracy during flight is strongly dependant on the initial attitude accuracy and the inertial sensor quality. Attitude accuracy and inertial sensor accuracy may be achieved by a cost intensive mechanic design of the launch platform and by high grade inertial measurement units. Both would increase the overall system cost and shall be avoided by means of online calibration of the attitude and inertial sensor biases. Therefore, DBD uses a transfer alignment procedure that is executed during setup of the launch platform which enables the estimation of misalignment angles between a reference navigation unit and the missile inertial navigation system and the estimation of inertial sensor biases. During setup of the launch platform the missiles are elevated to a vertical launch configuration. This is performed by a 90 degree rotation around one axis. To distinguish between misalignment angles and acceleration biases the transfer alignment is executed before, during and after the rotation of the missiles to extract the highest amount of information available. Based on the system configuration of a medium range air defence system, this paper describes and investigates the transfer alignment procedure. Finally results of the transfer alignment are presented.
