摘　　要：硬X射线调制望远镜(HXMT)卫星飞行程序设计具有在轨使用模式复杂、载荷需求约束多、在轨工作状态多且多系统多组合耦合、在轨自主管理功能应用与飞行事件操作流程耦合等特点。卫星在轨测试内容多、约束多、耦合强,因此在飞行程序设计中重点开展了入轨段程序时序评估和改进,观测模式、自主功能的应用设计,在分析设计需求约束并提取能够有效覆盖验证全部正常功能和工作状态的系统组合形式基础上,进行飞行事件编排优化。HXMT卫星在轨验证结果表明:卫星在轨运行良好,各飞行事件有序开展,飞行程序设计合理有效。The HXMT(hard X-ray modulation telescope)satellite flight program design has the characteristics of complex working modes,more constraints of payloads,in-orbit working states with multi-subsystem and multi-combination coupling,and the application of in-orbit autonomous management functions is coupled with flight events operation process.HXMT satellite has more in-orbit testing works,more constraints and strong coupling between the working states of different subsystems,so the design of flight program focuses on the evaluation and improvement of the time sequence of the injection stage program,the application design of observation modes and autonomous functions,the analysis of constraint requirements and the extraction of system combination states that can effectively verify all normal functions and working states,and then optimizes flight event scheduling.HXMT satellite in-orbit test results show that the injection stage procedure is well executed and the flight program design is reasonable and effective.
