作为要学习的区域拿欧洲的主要陆地,新卫星重力技术的潜力:追踪的 satellite-to-satellite (SST ) 并且与 SST 模型一起改进地区性的重力场模型的精确性被调查。这些模型的缺点被讨论。与是的 GPM98C 参考,几个另外的模型,的严肃异例剩余最近的 SST 全球重力场模型(EIGEN 系列和 GGM 系列) ,被计算并且比较。在选择区域,有期刊性质的一些系统的错误在 EIGEN 和 GGM 存在的比较表演的结果是在高度和顺序的 S 系列模型。没在经典严肃模型被显示出的一些信息在 EIGEN 和 GGM 的 S 系列模型的低、中间的度和顺序被检测。最后, SST 模型的有效的最大的度和订单被建议。
Taking the main land of Europe as the region to be studied, the potential of the new satellite gravity technique: satellite-to-satellite tracking (SST) and improving the accuracy of regional gravity field model with the SST models are investigated. The drawbacks of these models are discussed. With GPM98C as the reference, the gravity anomaly residuals of several other models, the latest SST global gravity field models (EIGEN series and GGM series), were computed and compared. The results of the comparison show that in the selected region, some systematic errors with periodical properties exist in the EIGEN and GGM's S series models in the high degree and order. Some information that was not shown in the classic gravity models is detected in the low and middle degree and order of EIGEN and GGM's S series models. At last, the effective maximum degrees and orders of SST models are suggested.
