On Midcourse Correction of Moon-Earth Return Trajectory Based on Explicit Guidance

Hu Jun;Zhou Liang;Beijing Institute of Control Engineering;Science and Technology on Space Intelligent Control Laboratory;  
The research on the midcourse correction of Moon-Earth return trajectory is necessary,as nominal orbit is perturbed by several disturbance sources and boundary constraints is complicated.The solution of characteristic velocity was got through the explicit guidance method by using the iterations algorithm based on the difference between the two-body orbit and precise trajectory.As the midcourse correction strategy was divided into moon-section and earth-section,the explicit guidance correction schemes of Moon-Earth return trajectory based on subsection location points prediction was presented.The scheme can satisfy the reentry point parameters constraints and can be used widely in practice,as the algorithm is simplified to overcome disadvantages of the differential correction algorithm which requires a numerical Jacobian matrix.Finally,the adaptability of the scheme was validated by numerical simulation and Monte-Carlo simulation.
