Abstract
En 中文
The communication between the reusable launch vehicle (RLV) and the ground station will be shielded by the blackout during entry flight. However, the communication utilizing the tracking and data relay satellite (TDRS) may be feasible. Therefore, a blackout zone communication (BZC) constraint for three-dimensional trajectory is proposed to stabilize the RLV-TDRS communication. First, the angle between the RLV’s antenna pointing and the RLV-TDRS vector is expressed, and the communication constraint between the RLV and TDRS (or other satellites) is formulated. Second, the BZC constraint is completed by combining with the altitude range of the blackout. Third, considering the BZC constraint, the trajectory optimization problem is established as a two-phase optimal control problem. Simulations across three scenarios illustrate the effectiveness of the method. Compared with trajectories without the BZC constraint, the proposed method can restrict the antenna pointing within the specified range.
