海南高精度高分辨率大地水准面模型

Hainan geode's model of high-precision and high-resolution

目前我国最高精度的省级大地水面—海南高精度高分辨率大地水准面建立中所采取的数学模型和数据处理方法,重点介绍了当前国内外确定大地水准面的严密理论和最新最严密算法。利用海南GPS控制网和水准联测成果,通过对十二种不同方案分析和比较,确定了最终方案。模型建立以后,利用外业水准测量的实际检测,确认该模型的达到了较高的精度。

Author introduces the model and means in high-precision geoid抯 model of Hainan province. He introduces emphatically strict theory and new approach in the field of assuring geoid at present. He determines the ultimate means through twelve different scheme analysis and comparisons. After built up, the model is assured that it has high precision through practical check of leveling.
