航空重力测量的偏心改正

Eccentric Correction for the Airborne Gravimetry

  • 摘要: 导出了航空重力测量偏心改正的实用计算公式,利用某航空重力测量实测数据,计算了位置、速度和加速度的偏心改正,并对垂直加速度、厄特弗斯改正、水平加速度改正和空间改正的偏心影响进行了详细分析,讨论了偏心改正对偏心距、姿态角的测定精度要求。

     

    Abstract: The mathematical formal of the ECC is derived.The ECC for various disturbing accelerations which include the vertical acceleration,Eötvös correction,horizontal acceleration correction and free-air correction etc.are analyzed by using the real observations from one airborne gravimetry test.The accuracy requirements for the eccentrical distance and the attitude are also discussed in detail.
