A new three dimensional tracking guidance based on full state coupling for hypersonic glide phase is proposed. Firstly, the dynamics formulation of position state in local coordinate frame is derived in conjunction with longitudinal and lateral trajectory state coupling relationship. In order to fast solve the problem of trajectory generation with multiple constraints and flight task requirements, all of the trajectory states have been normalized. Secondly, on the basis of dynamics equations, a three-dimensional coupling guidance model has been built with the help of proper performance index. Finally, simulation results with common aero vehicle (CAV-H) show that the trajectory obtained by proposed approach can well perform the tracking task during entry.
