LOS Stabilization and Gyro Configuration Analysis for Roll-Pitch Seeker

Abstract:

Roll-pitch seeker is currently applied in particular missiles, especially in air to air missiles. A representation of the seeker gimbal forward kinematics is analysed for the roll-pitch seeker based on the product-of-exponentials (POE) formula. And by transforming the inertial angular rate into the line-of-sight (LOS) coordinate system with the aid of recursive angular velocity equations, the LOS stabilization equation is obtained, then various schemes of gyroscope configuration and control are put forward based on the gyro direct stabilization. The research provides theoretical basis for the LOS stabilization control to isolate the LOS from the disturbance and vibration of carrier.
