大地测量数据处理中的潮汐系统和模型

Tide System and Model in the Geodetic Data Processing

经过30多年的发展,国际上对潮汐的研究不断深入。目前,已形成一套新的潮汐系统和模型。我国现行大地测量规范和细则中,一直沿用旧的潮汐系统和模型,已不再适应新的形势。因此,对1983年汉堡(Hamburg)IAG会议决议的潮汐系统和IERS(2003)潮汐模型及对大地测量数据处理的影响进行了介绍。

With the development of more than 30 years ,researches on tide correction has been continued in the international geodetic society. Since the old tide system and model in Chinese geodetic regulations is no longer adapted to the new situation, a new tide system and model have been established. Therefore, the tide system of 1983 hamburger（ Hamburg ）IAG meeting, the IERS （ 2003 ） tide model and the influence to geodetic data processing are introduced.
