Abstract: 介绍了香港大地水准面HKGEOID2 0 0 0和深圳市高分辨率、高精度似大地水准面SZGEOID2 0 0 0。利用HKGEOID2 0 0 0和GPS椭球高求得的正常高与香港地区由三角高程测量得到的“正常高 (或本地高 )”进行比较 ,结果表明 ,其差值的均方根为 0 .1 0 2m ,标准差 (STD)为± 3 .4cm。结合HKGEOID2 0 0 0、SZGEOID2 0 0 0和这两个大地水准面模型重复覆盖地区的高精度GPS水准数据 ,探测这两个大地水准面模型之间的差异和香港主要高程基准面 (HKPD)与我国 1 95 6黄海高程基准面之间的系统偏差。
An improved geoid model for Hong Kong,HKGEOID2000 with 1km resolution,was developed with removerestore approach and 1DFFT technique.This geoid model,along with GPS ellipsoidal heights,is employed to determine the errors of the "orthometric heights" from purely trigonometric heighting in Hong Kong,yielding an RMS error of 0.102m and the standard deviation ±3.4cm.
