Ellipsoidal physical geodesy - improved global and local gravity field modelling

使用本研究中提出的椭球体方法改进的重力场建模技术，将提高澳大利亚大地水准面模型的精度。更准确的大地水准面模型将主要为澳大利亚测绘和勘探界带来巨大的成本效益。例如，只有在精确的大地水准面模型的帮助下，才能从GPS[全球定位系统]或类似的基于卫星的测量确定高度。这将允许使用GPS的最大限度地使用，并节省宝贵的时间和金钱(多达10倍)。

Improved techniques for gravity field modelling, using the ellipsoidal approach proposed in this research, will increase the accuracy of the Australian geoid model. A more accurate model of the geoid will bring great cost-benefits mainly to the Australian surveying, mapping and exploration community. For example, height determination from GPS [Global Positioning System] or similar satellite-based measurements is only possible with the aid of an accurate geoid model. This will allow the use GPS to its full capacity and save valuable time and money (by as much as a factor of 10).
