The invention provides an earth-moon transfer orbit flight strategy closed-loop verification method and system. The method comprises the steps that satellites are connected to form a closed-loop verification system; powering up and setting the working state of each subsystem; powering off and pressing the travel switch; connecting spatial dynamics simulation equipment and setting the spatial dynamics simulation equipment to be in an initial open-loop state; performing satellite-rocket separation power-on program control; interpreting an initial orbit injection working condition until the flywheel is autonomously switched into a flywheel rough sun alignment working condition; verifying to enter a precise daily working condition; performing earth-moon cruise flight phase verification, moon orbit brake capture phase verification and moon orbit double-satellite separation phase verification; and replacing flight parameters and selecting main and standby single machines to carry out performance research verification. According to the method, deduction verification can be carried out aiming at flight missions with more constraints, restrictions and high complexity, the correctness of control strategies in all stages is assessed, the work collaboration of all subsystems and the rationality of flight program setting are assessed, and reliable operation of the moonlet after launching and orbit injection and smooth execution of task processes in all flight stages are guaranteed.

    本发明提供了一种地月转移轨道飞行策略闭环验证方法及系统,包括:卫星连接构成闭环验证系统;加电并设置各分系统工作状态;断电,压紧行程开关;连接空间动力学仿真设备并设置为初始开环状态;进行星箭分离上电程控;判读初始入轨工况,直至自主转入飞轮粗对日工况;验证进入精对日工况;进行地月巡航飞行阶段验证、月球轨道制动捕获阶段验证、月球轨道双星分离阶段验证;更换飞行参数及主备单机选择进行性能摸底验证。本发明能够针对更多的约束和限制和高复杂度的飞行任务,进行推演验证,考核各阶段控制策略的正确性,评估各分系统工作的协同性和飞行程序设置的合理性,保证小卫星发射入轨后的可靠运行以及各个飞行阶段任务流程的顺利执行。
