摘　　要：协同作战系统是由飞机、舰艇等多个运动平台组成的网络,在实现编队飞行、联合作战、协同探测等任务中需要网络成员间高精度的时空统一,由于时空基准信息获取、传递和处理的过程中发生的时间延迟,为多平台的时空统一带来难度。本文针对动态网络对时空统一的应用模式和功能需求进行了分析,提出了利用平台绝对时空基准和平台间相对时空基准信息进行时空统一综合处理的体系结构,给出了实现平台间相对定位和时间同步的若干相对导航技术途径。The formation of fighters, UAVs and ships can build a network of moving multi-platforms. High precise space-time synchronization among platforms would play an important role in formation flight, cooperative engagement and detection, but the time delay due to obtaining, transferring and processing space-time reference information has difficulty in space-time synchronization of multi-platforms. Based on the analysis of the applications of the space-time synchronization in dynamic network and their function requirements, a system architecture is proposed, the combination of absolute space-time reference information and relative space-time reference information is processed for space-time synchronization. Technology approaches to relative navigation is presented for relative positioning and time synchronization between platforms.
