摘要
利用广东地区GPS/水准数据和2个局部区域高密度的GPS/水准观测资料,对地球重力场模型进行了比较和分析。结果表明,在广东地区,EGM2008/EIGEN-6C(1420)模型的精度最高,达0.066 m。
Several earth gravitational field models are compared and analyzed based on the GPS/leveling data, which are distributed over not only Guangdong region but also densely over two local areas. The result shows that the accuracy of the EGM2008/ EIGEN6C（1420） model is the highest with 0.066 m in Guangdong region.
