This paper proposes an online trajectory optimization algorithm combining a CNN-LSTM network with the Radau pseudospectral method for constrained spacecraft re-entry. The network provides an initial guess, enabling the pseudospectral method to converge rapidly with fewer iterations and less computation. Simulation results confirm the method's effectiveness and engineering applicability.
