GFZ波茨坦和GRGS图卢兹在全球重力场测定领域有着长期密切的合作。本文主要研究GOCE重力场的确定和高分辨率组合重力场模型的计算。这类数据产品在大地测量和地球科学中发挥着根本性作用，从精确轨道确定等实际目的到地球内部密度结构调查等科学应用，不一而足。在这里，我们介绍了我们的组合重力场模型EIGEN-6C 4，这是EIGEN-6C（EIGEN =欧洲改进的地球重力模型的新技术）的第四个版本。
GFZ Potsdam and GRGS Toulouse have a long-time close cooperation in the field of global gravity field determination. Here we focus on (1) GOCE gravity field determination and (2) computation of high resolution combined gravity field models. Such data products play a fundamental role in geodesy and Earth sciences, ranging from practical purposes, like precise orbit determination, to scientific applications, like investigations of the density structure of the Earth’s interior. Here we present our combined gravity field model EIGEN-6C4 which is the fourth release of EIGEN-6C (EIGEN = European Improved Gravity model of the Earth by New techniques).
