摘要
在简述地球重力场模型发展历程的基础上,对地球卫星重力场模型及其应用的研究进展进行综述。回顾了卫星重力测量技术的发展历程,并对CHAMP、GRACE、GOCE和GRACE-FO任务进行了详细介绍;阐述了目前主要的卫星重力反演方法及其改进现状;介绍了目前国际上主要机构反演的地球卫星重力模型,并分别对CHAMP-Only、GRACE-Only和GOCE-Only的系列模型进行对比分析;综述了地球卫星时变重力场模型的应用研究进展;对钱学森空间技术实验室天空海一体化导航与探测团队在地球卫星重力场模型及其应用的研究进展进行了概述;最后,对未来地球卫星重力场模型研究进行了展望,提出了研究建议。
The development of the earth's gravity field model was introduced and the research progress of the earth's gravity field model and application was reviewed.First,the development history of satellite gravity measurement technology was reviewed.Specially,the missions of CHAMP,GRACE,GOCE,and GRACE-FO were introduced in detail.Secondly,main inversion methods of satellite gravity and the improvements were elaborated.Thirdly,the earth's satellite gravity models of major international institutions were presented,then CHAMP-Only model,GRACE-Only model,and GOCE-Only model were compared with their corresponding series models,respectively.Fourthly,the progress of the earth's satellite time-varying gravity field model application research was introduced.Fifthly,the progress of the research team of navigation and detection based on the information of aerospace-aeronautics-marine integration summarized.Finally,research of the earth satellite gravity model in the future were proposed and expected.
