摘　　要：本文给出了GPS共视方法的原理和数学模型，应用GPS共视法处理站间时间同步数据，得到了站间钟差，并进一步分析了钟的频率稳定度。结果表明，GPS共视法应用于站间时间同步精度可以优于10ns，其结果也可以较好评价钟的稳定度。In this paper, the theory and mathematic model of GPS Common - View （CV） time synchronization were presented. And then this method was used in processing the GPS CV data collected from two stations. The clock bias was obtained and the frequency stability was analyzed further. The result showed that the accuracy of time synchronization between ground stations employing GPS CV method was better than 10ns, and it could perform well in evaluating the stability of the clock.
