The pseudospectral nodes with high solution accuracy and fast convergence speed are adopted. - Nonlinear Programming Approach There will be multiple push-slip segments of the optimal mission planning problem discretely transformed and solved quickly. The simulation results show that this method can comprehensively evaluate the envelope of maneuvering orbitability under the constraints of limited propellant consumption and program angular rate limit, and then give the optimal orbit to meet the requirements of controllability.
