摘　　要：分布式航天器间相对位置的实时高精度测量是分布式航天器实现空间队形保持的关键技术之一。为了对相对位置测量方法进行研究、分析和论证,建立了分布式航天器相对位置测量地面实验平台。介绍了分布式航天器相对位置测量和解算的基本原理;论述了仿真平台的组成和功能;基于仿真平台对相对位置测量精度进行了仿真试验,试验结果显示该平台具有良好的性能指标;最后介绍了相对位置解算仿真评估软件的设计方法。High precise real-time autonomous relative orbit determination between distributed spacecraft is a key technology in the task of spacecraft formation maintenance. For analyzing and evaluating autonomous relative position measurement methods, a hybrid simulation platform for relative position measurement between distributed spacecraft was proposed. The theory of relative position measuring and calculation model are discussed. The config- urations and functions of the simulation platform were introduced. Based on the hybrid simulation platform, relative ranging measurements were verified. The test results show that this platform meets the specified performance index. At last,The software for distributed spacecrafts relative position calculating was introduced.
