| 摘 要： | 在确保GPS/水准点成果可靠的前提下,用其对重力法计算所得的高程异常模型进行框架约束,以削弱重力系统与高程和坐标系统间的系统差,实现系统转换,提高最终模型的精度。通过对不同离散数据网格化方法的比较,给出相对计算快捷、精度高的框架约束方法。

| Abstract: | Under the condition of reliable GPS/level data,boundary restriction to gravitational height anomaly model is made,which aims at weakening the system errors existing in the transform between gravity system and height system,achieving the system transform,improving precision of ultimate model.The algorithm for boundary restriction which is more fast and more accurate is given,by the comparison of different grid methods to discrete data. |
