A Verification Method and Experimental Study of Data Transfer during Transfer Alignment on Moving Base

For mixed-guided airborne missiles, to ensure accurate handover from midcourse to terminal guidance, the carrier and missile shall be within a unified coordinate system during data transfer. To eliminate mounting precision errors and assess the missile-carrier alignment errors excited by different speeds, heights, attitudes, overloads, maneuvers and other conditions when elastic and torsional deformations are generated due to the aerodynamic force during the flight of the mounted missile, measurement methods are proposed in this paper. An engineeringly-feasible verification scheme for alignment error transfer relationships is also studied and developed through experiments, and the convergence speed and accuracy of the alignment algorithm are verified experimentally, proving that the scheme can be applied to evaluate transfer alignment on a moving base.
