| dcterms.abstract | 以GPS/重力边值问题为基本数学模型,利用不同分辨率扰动重力数据分别模拟了对GPS/重力边值问题的影响。数值模拟结果表明,数据分辨率与结果精度有密切联系,在丘陵地区,当数据分辨率在2 km时,可以满足cm级似大地水准面的要求,同时提出了一些现实可行的建议。 | - |
| dcterms.abstract | Based on the theory of GPS/gravity boundary value problem,the errors caused by gravity disturbances of different resolution are simulated and analyzed using numerical simulation methods.The result shows that the relationship between data resolution and result precision is osculating,and 2 km resolution data can satisfy the demand of the centimeter level geoid in hilly area.Meanwhile some feasible suggestions are put forward. | - |
