海空重力测量平台倾斜改正模型等价性证明与验证

Test and Equivalent Verification of Gravity Correction Models for Platform Tilt in Sea-Borne and Air-Borne Gravimetry

  • 摘要: 关于重力测量稳定平台倾斜改正模型选用问题,国内外学者和机构至今未取得完全一致的意见。从理论上证明了当前国际上推荐使用的三种重力平台倾斜改正模型的等价性,估算了平台倾斜重力改正的量值大小,并采用航空重力测量实测数据,对三种改正模型进行了数值验证和对比分析,得出了比较明确的结论,为实际作业选用合适的数据处理流程和改正模型提供了理论依据。

     

    Abstract: Currently there is no consensus among scholars on the appropriate choice of gravity correction models for platform tilt in sea-borne and airborne gravimetry. In this paper, the equivalency of the three existing correction models recommended for usage are analysed theoretically and platform tilt effect is empirically evaluated. A set of airborne data from practical survey lines is used to examine and compare the numerical value of platform tilt effect of the three existing correction models. The results clearly and definitely prove our efforts, and this offers useful theoretical support for the choice of data processing steps and correction models in application of airborne gravimetry.
