| Abstract: | Based on the results of studying on precise geoid in recent years,four interesting problems are discussed and reviewed:(1)the definition of geoid.(2)the functions of geoid.(3)the transform between geoid and quasigeoid.(4)the effect of sea surface topography on geoid computation and its correction, and (5) the zero order term in height anomaly and its error. |

| Keywords: | geoid quasigeoid height anomaly sea surface topography |
