In order to validate the acquisition and tracking system design of data relay satellite, a validation method based on approximate far field condition is proposed, considering the differences between ground and orbit environment.The validation system, which is used to carry out acquisition and tracking test, consists of data relay satellite on-orbit products, user satellite simulation equipments, high precision orbit simulation equipment, optical pointing devices, antenna gravity unloading equipment and other ground test equipments.Test results for static and dynamic user satellite are given, which are consistent with numerical simulation results.Those results show that the proposed method is correct and effective, and further validate singleimpulse tracking scheme and tracking strategy.The method proposed in the paper can provide some support for data relay satellite on-orbit operation.%为了验证中继卫星捕获跟踪系统设计, 充分考虑地面环境和在轨应用的差异, 提出基于近似远场条件下的中继卫星捕获跟踪技术验证方案.利用中继卫星设备、用户航天器模拟设备、高精度二维轨道模拟设备、光学指向设备、天线重力卸载设备以及地面测试设备等组成的验证系统进行捕获跟踪试验, 给出了静目标和动目标捕获跟踪试验结果, 并与仿真跟踪过程进行了比对.试验结果和仿真结果一致, 验证了文章提出的中继卫星捕获跟踪技术验证方法的有效性, 进而验证了捕获跟踪技术方案、单脉冲角跟踪体制、跟踪策略等, 为中继卫星在轨可靠工作提供技术支撑.
