星地时间同步是导航定位系统的重要组成部分，准确评价星地时间同步任务规划的好坏，是卫星方案设计及优化提高卫星导航系统运行效率的基础。针对导航卫星星地时间同步任务规划评价问题，建立了基于任务、资源、性能的多层次评价指标体系，构造了通用的综合评价框架，最后通过仿真验证了方法的可行性，为导航系统的顶层设计与地面资源配置优化提供决策支持。

Time synchronization between satellite and the earth is an important part of the navigation and positioning system. Time synchronization mission scheduling evaluation is the basis of satellite project design and improving satellite navigation system running efifciency. In view of the evaluation of the navigation satellites task scheduling, a multi-level measurement index system based on task, resource and performance is set up. A general comprehensive evaluation frame is constructed. At last, it demonstrates method feasibility by analyzing the computational results. The method provides the decision support for the navigation system's top-design and the optimization of the ground recourse's allocation.
