由固体潮、海潮和大气潮产生的地球引力场变化可以从卫星轨道摄动中求解 .利用近1 0年的卫星跟踪数据求解出地球引力场的潮汐变化 ,结合由Topex/Poseidon卫星测高得出的海潮模型 ,并顾及大气潮模型改正 ,求解出了在固体潮波M2 和K1上的相位滞后 ,分别为 0 1 2和 0 1 3°.这一结果与Ray最近用卫星数据得到的结果 0 1 6°和Zschau约束的理论解 0 2 1°相符 .而地面的重力潮汐方法结果则较离散
The gravitational field changes caused by the tides, tides and atmospheric tides can be solved from the orbital perturbations of the satellite. Using the satellite tracking data of nearly 10 years to solve the tidal changes of the gravitational field of the Earth, combined with the altimetry of Topex / Poseidon satellites And taking into account the atmospheric tide model correction, the phase lags on the solid tidal waves M2 and K1 are solved, respectively 0 1 2 and 0 1 3 °. This result is consistent with Ray’s recent satellite data 0 1 6 ° is consistent with the theoretical solution of Zschau constraint 0 2 1 °, while the ground gravity tidal method results are more discrete
