摘要
星钟误差是影响卫星导航接收机的一项误差源,文章在建立星钟稳定度时域和频域数学模型的基础上,使用阿伦方差来仿真分析星钟稳定度带来的影响,为星钟稳定度对导航接收机的影响打下基础,并为评估星钟稳定度方法提供参考借鉴。
The star clock error is an error source affecting the satellite navigation receiver.Based on the establishment of the time domain and frequency domain mathematical model of the star clock stability,the paper uses the Allen variance to simulate and analyze the influence of the star clock stability.It lays a foundation for the influence of the stability of the star clock on the navigation receiver,and provides reference for the method of evaluating the stability of the star clock.
