航空重力测量中水平加速度改正的计算与频域分析

Calculation and Spectra Analysis of Horizontal Acceleration Corrections (HACC) for Airborne Gravimetry

    摘要
  • 摘要: 基于扰动水平加速度的正弦运动模型,对平台失准角和水平加速度改正的频谱特性进行了分析。利用某航空重力测量试验的实测数据,计算了平台失准角和水平加速度改正。

     

    Abstract: It is meaninful to estimate the gravity value in Qomolangma peak.When the wave length for the topographic load λ ≤ 50 km,the crustal strength is strong enough to keep the crust not deformed.Therefore,it is improper to use Airy-Heiskanen or Pratt-Hayford local compensation model to estimate the gravity.On the basis of this idea,utilizing four kinds of formulas,we give the gravity of everest (976970±7)×10-5m·s-2.
