摘要
EGM2008是一个地球重力场模型,该模型在全球总体范围来讲具有较高的精度,但在具体局部地区,还需要用实测数据对模型进行进一步精度校正,本文应用最小二乘配置法在某海区利用实际船测重力对EGM2008模型进行了校正实验,实验结果表明校正后的数据更加精确地反映了该区实际重力分布,提高了模型的精度。最小二乘配置法在海洋局部重力数据融合中效果显著。
EGM2008is a model of Earth gravity potential.Globally,it has a high precision.However, in local areas,it needs to use the measured data for further precision correction.In this article,we use the measured data in some sea area to correct the precision of EGM2008by Least-squars collection.The results shows that the corrected data reflects the distribution of gravity of this area more accurately,the precision of the model is improved.The Least-squars collection have a remarkable effect in the integration of local marine gravity data.
