摘要
简要介绍了天津市12个GPS连续运行站的建设状况和在各领域中的应用,通过最新的精密处理策略对一年多的数据进行计算,得到精确的ITRF坐标时间序列,并分析了ITRF框架下天津市地面水平和垂直坐标变化规律,为GPS技术的进一步运用打下基础。
The establishment of 12 continuously operating GPS stations in Tianjin and their applica tions in various fields are introduced. According to one-year-span GPS data with the latest strategies, coordinates time series are determined precisely and the horizontal and vertical crustal deformation on ITRF is announced. Above processing is useful for further research on GPS.
