摘　　要：针对多星组网在轨全面快速调试背景下的相机参数校准问题,提出了一种从成像任务规划到性能调试的相机在轨全流程调优策略.首先,构建了卫星发射后的轨道模型和应用于相机调试的成像任务规划约束模型;然后,筛选出符合调试条件的地面目标点进行成像任务;最后,通过分析成像结果优化了传统的相机在轨焦面校准与调参方法,高效高质地完成了相机在轨调试工作.“北京三号”C卫星星座采用该策略高效顺利地完成了相机调试工作,满足了相机测试与应用要求.在轨验证结果表明:该策略正确可行且实施方法高效,可为星座业务化运行与应用服务提供及时良好的像质保障,同时可对同类型对地观测遥感卫星的在轨调试工作提供参考.Aiming at the camera parameter correction problem under the background of multi-satellite network in-orbit comprehensive and quick commission,a camera in-orbit whole process optimization strategy from imaging task planning to performance commission was proposed.First,the orbit model after satellite launch and the constraint model of imaging task planning used in camera commission were constructed.Then,the ground targets qualified by the commission conditions were selected to carry out the imaging task.Finally,based on the imaging result analysis,the traditional camera in-orbit focal plane correction and imaging parameter commission method was optimized,enabling the camera in-orbit commission work to be completed with high quality and efficiency.The camera commission work of the adopted BJ-3C Satellite constellation was accomplished efficiently and smoothly by adopting this strategy,meeting the requirements of camera testing and application.The in-orbit verification results show that this strategy is correct,feasible and efficient,and provides timely good image quality which ensures the operational application and service capability of the constellation.Meanwhile,it also provides a reference for the in-orbit commission work of the same type of Earth observation remote sensing satellite.
