摘　　要：基于青岛附近黄海海域的GNSS验潮观测数据,利用GAMIT TRACK双差动态定位模块,解算潮位变化。引入IGS组织发布的最终星历参与计算,获取GNSS高精度验潮,将结果与压力式验潮仪的观测值进行比对。采用QDCORS站和上海IGS连续跟踪站的数据分别与流动站组成6类不同长度的基线组合,验证模块的作用距离,使得结果具有更广的适用性。Based on GNSS differential phase kinematic positioning program of GAMIT TRACK, tidevariation is cal-culated using GNSS observation date of yellow sea near QingDao. IGS final ephemeris is involved to achieve GNSS high-precision ocean tide observation, which is compared with recorded values of pressuretidegauge after. The ob-servation data of QDCORS sites and SHAO of IGS sites is combined with a kinematic site to form six kinds baselines of different length, which are used to verify the operating distance of track program.
